Aaron Swartz on the Sidekick. What's interesting to me is the assumption of all commenters that it's dead, or if not, will be very soon.
But once again: the obsession with hardware at the expense of moving the software anywhere at all, particularly the web browser, was deadly. Note also that all mentions of the hardware are negative. Everybody complains about build quality, even of the Sharp-made generations. Hrm! Dunno what that means. I do know that I showed my sister an M2 (um, I think that shipped as the Sidekick 3) and her reaction was that it just wasn't cool enough to tempt her. We never had good ID.
The one guy who wrote software for it liked the toolkit. The hiptop app framework is one of things Danger did right, as is the great performance the clever, clever 1.0 team squeezed out of feeble hardware. My husband's iPhone doesn't do anything in the background, because it "can't", and any of a million Apple fanboys will tell you why this is the "right" design. Well, nonsense. Demonstrated as nonsense in 2002, when I was getting all my instant messaging and email traffic flowing in while I browsed the web. And demonstrated as nonsense every day while my little Twitter app fetches my tweets in the background.
But the hiptop 2008 == hiptop 2002, and you just can't do that.
Though from another perspective it's a success story. The people who chose not to move the software at all now have oodles of money from the acquisition. Those decisions look good from the vantage point of retirement. Who's to tell them they did it wrong?
