I hate lists like this, because they are usually revisionist history. Again, there's a heavy West Coast Bias, as if the IBM PC and Apple and Microsoft were the only tech companies that ever existed.
Where for example (as others have pointed out) is the Commodore 64, the "Model T" of computers? It's simply the single most successful computer of all time, selling more than 33 million units of a single "model" of machine, more than any other single model of machine.
And while they mention the Amiga 1000, where's the Video Toaster and Lightwave 3-D, the software that revolutionized 3-D animation on reltively cheap low-power machines? Oh sorry, that technological marvel came out of Kansas, and nothing high-tech comes out of Kansas, right?
And here's something that was developed on the west coast that deserves praise (is it on the list?) The Palm Pilot -- without which, we'd probably not have half of the other items that *are* on the list.
It always seems to me that the editors of such "lists" only remember what they themselves "played with", and if they didn't touch it with their own hands, it didn't exist and therefore isn't worth mentioning.
Also, exciting innovations such as the mouse which are made at academic think-tanks or research departments of large companies are also not worth mentioning. Do you think these editors bothered to research anything happening at MIT's media lab? Of course not. MIT after all, is on the EAST coast.
This list makes me sad that we're already forgetting important history from just a few years ago. In twenty years, people will be saying the Bill Gates invented the computer and taking that as fact.
