Jef Raskin wrote "The Humane Interface" about the fundamental issues of interaction design for usability of any computer based system. A summary of design rules:

The Writing Information Appliance - It was a true information appliance which allows you to just type. It packs a surprising amount of power in a small set of tools and commands.

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:

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"
