As much as I love esoteric computer languages and UNIX, I don't consider those to be the paragons of the promise of computers.
EDIT: "We would like the Dynabook to have the flexibility and generality of this second kind of item[paper or clay], combined with tools which have the power of the first kind[cars, television sets]." I'd say they were aiming for inspiration AND power. I'd also argue that inspiration without power is worthless...
When I look at a shitty netbook what am I supposed to be inspired about? Tinkering with Linux is no future of computing- it's nigh time to get out of that pipe dream.
Though, I expect and look forward to Linux to be installed on the thing within two weeks of it getting to the stores ;)
