At Information Appliance Inc., we decided to use the Apple II, as a development environment. Running our own Forth (tForth), we developed and tested the software until it was our own major tool for every task at hand. These tasks included word processing, spreadsheet, software development, communications (then over phone lines) and data storage and retrieval -- we were strong believers in the maxim that if the product isn't good enough for us, it's not good enough for our customers. Of course, we were aware that the converse was not true. If it was good enough for us, that didn't prove that it was good enough for our customers.To assure that it was good enough for our customers, we did a lot of testing, and one of the results was that the testees nearly always wanted to know when they could get the software. After you've heard such a request repeatedly, the idea arises that perhaps we had an Apple II software product. First we supplied it as a ROM on a plug-in card, which was called "SwyftCard". This had the advantage of being a piece of uncorruptible and uncrashable software. A lower-cost alternative was then developed, with the software being delivered on a 5 1/4 inch floppy. This was called "SwyftWare".
We sold the rights to market SwyftWare to a company run by a friend in San Diego.
The code was extraordinarily well-documented and there was a test word for every word in the program, as well as a word that ran all the tests as an automatic suite so that we could check for side-effects whenever we made a change. It is to these methods I attribute the nearly unique accomplishment of Information Appliance: a piece of commercial general-purpose software in which no bugs were ever discovered. We had the same splendid results in designing the Canon Cat.
Some of the IA devices were prototypes and not the laptop versions, I think.
I think these were a finished design:

Work Processor
I like that description: "work processor."
"It can help you write and edit, communicate and calculate. It’ll even dial your phone."
Another image of yet another brochure for the Canon Cat
http://clickamericana.com/media/advertisements/the-canon-cat-word-processor-1987
Some of the brochure's text reads with my emphasis added:
The Canon Cat is the world’s first Work Processor. It’s a simple but powerful office machine. The Canon Cat is not a typewriter, electronic or otherwise. Yet minutes after you plug it in, you can be typing on the Cat like a veteran.The Canon Cat is not a word processor. Yet it will let you write and edit faster than any word processor in the world.
The Canon Cat is not a personal computer. Yet it will let you do calculations right in the text, store information and communicate with other office machines.
What is the Cat? As we said, it’s the world’s very first Work Processor. It can help you write and edit, communicate and calculate. It’ll even dial your phone.

The Canon Cat was designed by Jef Raskin, who in 1979 initiated the original Macintosh computer project while working at Apple (Raskin was Apple employee #31).The Macintosh, so-named by Raskin, was to be an inexpensive, text-based, keyboard-controlled system meant for the average "person in the street" (PITS). After Steve Jobs took over the project while still in its infancy, Raskin left Apple to start his own company, Information Appliance, Inc., where he was free to develop his ideas without external influence.
Continuing his "user interface" (UI) concepts, he developed the SWYFT, a protoype system which eventually evolved into the Cat, after Canon bought and financed the development.
The Canon Cat is an single unit, with the keyboard, electronics, and monitor all housed in an ergonomically-design enclosure. A convenient carrying handle is formed into the enclosure, behind the display.
Although the Cat has a serial port and software routines to support input devices such as a mouse or pointing pad, none were released or supported by Canon. The Cat also has advanced graphics tools in ROM, but they were never utilized - the Cat as released supports text only.
The optional Cat180 (Canon PR100) daisy wheel printer can print only text, and it does it very well, but at only 18cps (characters per second).
All of the required software is permanently stored in system ROM. Floppy disks are required only to save and restore documents and other work. Approximately 80 pages (180kB) of text can be saved to each floppy disk.
The operator can easily and quickly save all current work to the floppy drive, by simply hitting a two-key combination - the entire 256K system memory is saved to the SSDD disk. When the Cat is restarted, the system RAM is restored from the floppy disk, allowing the operator to continue where last left off. By design, there is no operating system, as far as the user is concerned.
It's the "Leaping" ability of the Cat which gives it its name, as well as its unique ability to quickly move about within a large text document without using a mouse or cursor keys.
Navigation is performed using the "Leap" keys. With different Leap key combinations, it's possible to instantly jump to any paragraph in the document, any sentence, or any individual word to perform editing or correction. It's just as easy to return to the end of the document to continue writing.
The software is advanced enough to perform mathematical calculation right in the text document, using the [CALC] button. Columns and rows can be combined to act as a spreadsheet, allowing the use of advanced and complicated formulas.
The built-in 90,000 word dictionary helps minimize spelling errors, while the [EXPLAIN] key offers instant help on most topics and key useage.
The Cat has an internal 300/1200 baud modem, capable of connecting and transferring text (only) to and from another computer, or even another Cat. Simply highlight the desired text on the screen and hit [SEND] to transmit the text to the other system. All incoming text appears on the screen and becomes part of the current document. The Cat can also act as a 24-hour message center, saving all incoming messages to the floppy drive.
The Cat is actually much more powerful than let on by Canon, who marketed it as a closed-architecture secretarial workstation, not as the real computer which exists under the hood.
Because of poor sales, Canon discontinued the Cat after only six months. This was due to poor marketing, according to Raskin.

Appliance vs computer
http://en.wikipedia.org/wiki/Information_appliance
The term information appliance was coined by Jef Raskin around 1979. As later explained by Donald Norman in his influential The Invisible Computer, the main characteristics of IA, as opposed to any normal computer, were:
- designed and pre-configured for a single application (like a toaster appliance, which is designed only to make toast),
- so easy to use for untrained people, that it effectively becomes unnoticeable, "invisible" to them,
- able to automatically share information with any other IAs.
This definition of IA was different from today's. Jef Raskin initially tried to include such features in the Apple Macintosh, which he designed, but eventually the project went a quite different way. For a short while during the mid- and late 1980s, there were a few models of simple electronic typewriters with screens and some form of memory storage.
These dedicated word processor machines had some of the attributes of an information appliance, and Raskin designed one of them, the Canon Cat. He described some properties of his definition of information appliance in his book The Humane Interface.
Larry Ellison, Oracle Corporation CEO, predicted [in the mid-1990s] that information appliances and network computers would supersede personal computers (PCs).6 This prediction has not yet come true.
Norman wrote the book: "The Design of Everyday Things"

http://www.jnd.org/dn.mss/in_appreciation_of_j.html
The philosophy of Archy, among other things, is to eliminate the artificial distinction between the Operating System and applications (just as in Jef's pioneering Canon Cat, where he eliminated the notion of files and documents). Why not make it that any command can be invoked at any time?In other words, to add a different capability to the system, we don't need to write a specialized application, with its specialized command structure, but rather leverage the commands that already exist and add any news ones that might be required.
Among other things, this guarantees a consistency of operation not otherwise possible when each application has to rebuild many of the functions already existing in other applications.
Archy borrows from the pioneering work of Ken Perlin's Pad system, so that moving around material is done by zooming and panning (see the Pad system initially developed by Perlin and Fox and then by Hollan and colleagues
Perlin, K., & Fox, D. (1993). Pad: An alternative approach to the computer interface. Proceedings of 1993 ACM SIGGRAPH Conference.
[ http://mrl.nyu.edu/publications/sig93-pad/siggraph-93-origpad.pdf ]
I still have not fully digested Archy, but I urge more people to investigate the precepts, especially people who think that we have reached a dead end in the development of interaction paradigms for text. (I have made this claim, for example, arguing that although many novel interaction schemes are being -- and will be -- developed, for writing pure text, such as this essay, the mouse, keyboard, and screen serves me well. Does it?)

Jared Spool is right on. My mentor was Jeff Raskin (designer of the original Mac UI and many other cool innovations). What I learned from Jeff is that if you want to design a successful product that will be widely adopted the one thing you need to know all about is Habits.People are creatures of habits. They have needs -- and often are articulate about those that aren't being met, or aren't being met regularly, or very well. But they aren't good at articulating a better way to meet those needs -- that is what the designer needs to do.
And the designer needs to start by understanding the user's existing habitual way of trying to meet those needs -- and they have to extinguish that existing habit, or there will be no possibility of adoption.
Next you need to address habit formation -- only when you make it easy to make a replacement new habit will adoption be ensured.
And finally you need to understand habit maintenance. Otherwise you lose people who have already tried your product.
Note that these issues are all about human cognitive psychology -- it doesn't matter whether you work in basic HTML and CSS, Ruby on Rails, Drupal, Python or any other technology -- if you don't get the habit management right technology won't save you, and if you get the habits right, the underlying technologies are invisible to the user.
Check out the early books and materials by people who founded the Association for Software Design (ASD), while the platforms and technologies they use may have changed a lot, people's motivations and the way habits determine their behavior have barely changed in recorded history. There is a lot of wisdom there.

It all started in 1979 when Jef Raskin, an Apple employee, wanted to make an easy-to-use, low-cost computer for the average consumer. In September 1979, Raskin was given permission to start on the project. He put together a team of people, partially pictured to the right, that consisted of Chris Espinosa, Joanna Hofman, George Crow, Jerry Manock, Susan Kare, and Andy Hertzfeld. Bill Atkinson, a member of the Lisa team, introduced Jef Raskin to Burrell Smith, a service technician who was hired earlier that year.Smith built the first Macintosh board according to Raskin's specifications: 64K of RAM, Motorola 6809E microprocessor, and had the ability to support a 256×256 B&W white bitmap display. By December 1980, Smith was able to design a board that utilized 68000 and had the capacity to support a 384×256 bitmap display. This design used few RAM chips than Lisa, the other computer that was being developed by Apple, and was mych cheaper. The final Mac design was self-contained and had a non-expandable 128 kilobyts of RAM. This design caught the eye of Steve Jobs, the co-founder of Apple. Jobs realized the Macintosh was more marketable than Lisa so he focused his attentions on the new system. Raskin left in 1981 due to personality differences with Jobs. Jobs, hearing about a new graphics user interface being developed at Xerox, traded Apple stock options to see the GUI. After his visit to Xerox, Jobs hired Harmut Esslinger to work on the Macintosh line. Jobs' leadership at Apple ended in 1985 when there was an internal power struggle with Apple's CEO John Sculley. Jobs went on to found the company NeXT.

In early 1979, after successfully building an outstanding pubs department, Jef turned the reins over to Phyllis Cole and started thinking about what it would take for personal computers to expand beyond the current hobbyist market, writing up his ideas in a series of short papers. He presented his idea for an ultra low cost, easy to use appliance computer to Mike Markkula in March 1979, and got the go-ahead to hire a few people and form an official research project later in September 1979, naming it Macintosh, after his favorite kind of eating apple. Most of his ideas for the new machine were collected in a set of papers he called "The Book of Macintosh".There's no doubt that Jef was the creator of the Macintosh project at Apple, and that his articulate vision of an exceptionally easy to use, low cost, high volume appliance computer got the ball rolling, and remained near the heart of the project long after Jef left the company. He also deserves ample credit for putting together the extraordinary initial team that created the computer, recruiting former student Bill Atkinson to Apple and then hiring amazing individuals like Burrell Smith, Bud Tribble, Joanna Hoffman and Brian Howard for the Macintosh team. But there is also no escaping the fact that the Macintosh that we know and love is very different than the computer that Jef wanted to build, so much so that he is much more like an eccentric great uncle than the Macintosh's father.
Jef did not want to incorporate what became the two most definitive aspects of Macintosh technology - the Motorola 68000 microprocessor and the mouse pointing device. Jef preferred the 6809, a cheaper but weaker processor which only had 16 bits of address space and would have been obsolete in just a year or two, since it couldn't address more than 64Kbytes. He was dead set against the mouse as well, preferring dedicated meta-keys to do the pointing. He became increasingly alienated from the team, eventually leaving entirely in the summer of 1981, when we were still just getting started, and the final product utilitized very few of the ideas in the Book of Macintosh. In fact, if the name of the project had changed after Steve took over in January 1981, and it almost did (see Bicycle), there wouldn't be much reason to correlate it with his ideas at all.
So, if not Jef, does anyone else qualify as a parent of the Macintosh? Bill Atkinson is a strong candidate, since he was almost singlehandedly responsible for the breakthrough user interface, graphics software and killer application that distinguished the Mac. A case could also be made for Burrell Smith, whose wildly creative digital board was the seed crystal of brilliance that everything else coalesced around. But ultimately, if any single individual deserves the honor, I would have to cast my vote for the obvious choice, Steve Jobs, because the Macintosh never would have happened without him, in anything like the form it did. Other individuals are responsible for the actual creative work, but Steve's vision, passion for excellence and sheer strength of will, not to mention his awesome powers of persuasion, drove the team to meet or exceed the impossible standards that we set for ourselves. Steve already gets a lot of credit for being the driving force behind the Macintosh, but in my opinion, it's very well deserved.
Jef created the Macintosh project, but Jobs created the Macintosh product.
