Makes me miss Lisp machines :-/
A fully functional Lisp machine with a USB keyboard and mouse to match would be the ultimate übergeek gift.
A small Alto would also be pretty neat. The vertical screen could be tricky.
might make it simple enough to develop a lisp machine.
Seriously: more than once we have lost a technology because we turned the other way at some point. The Lisa'a stationery idea is one example off the top of my mind of a great idea that was not only ahead of its time but ahead of our time. We install programs and run them to create documents instead of using a desktop to create a document of a new type that the program we installed happens to support. I like to joke Smalltalk 80 made Java 2010 look primitive. I am only half joking on that.
