there is confusion. just following the question what kind of model was really standing there, in 1970 at PARC. what idea was really discussed in those days? it seems dynabook wins, but i can't give the exact answer. was alan kay already dreaming about something that can be called a pda, as other suggest, or about what later became a laptop? x or y.

"By 1976 Kay shifted his attention toward a new project called Notetaker, another notebook sized computer.
The central idea was to take a percentage of the Alto's functionality and put in a compact portable machine. The Notetaker design included a custom-built display screen that was touchsensitive to eliminate the mouse; stereo audio speakers with a built-in microphone; 128,000 bytes of main memory, a rechargeable battery; and an Ethernet port."

and:

"In 1970, Kay made sketches of the KiddieKomp, which later developed into a laptop computer called Dynabook. The Dynabook was described as a very powerful, portable electronic device that would about the size of a notebook. It would carry an encyclopedia of information inside its circuits and plug into a computer network. Dynabook was the visionary prototype of a notebook computer that was later developed by Apple and other hardware companies."

i would interpret that this source is suggesting the KiddieComp, others favour the NoteTaker.
but what was it really, that caused these of the LRG-members??? what was it, when he talked about the "pocket universe"???
