"not even an improvement over an old invention."
Right. Because the Macintosh was exactly like the Xerox Star, right down to the three-button Mouse and Smalltalk commands. Which Jobs licensed for a very agreeable amount - and he then directed the improvements that led to the popular GUI-driven personal computer.
The iMac - a minimalist, low-cost, laptop-derived machine with a CRT that was extremely easy to set up and which was design-forward - good-looking enough to put it in the center of your living area and not hide under a desk. Yeah, that was totally already done.
I wonder sometimes if Slashdot has gotten any better, then I come over and read stuff like this in the 'discussion' and realize it's just the same old, same old.
