Almost exactly two years ago, Microsoft tried to build a huge buzz over the pending release of the first device based on the Windows Ultra-Mobile OS platform, code-named "Origami". The first product to be released was a small handheld PC from Samsung. This product was discussed (and ridiculed) quite a bit around here at the time. The Samsung device is apparently still manufactured as the Q1 Ultra-Mobile, but I don't know of any other computer sold with this OS, and I have never seen a Samsung Q1 in the wild. Has anybody else seen one? For all appearances, Microsoft's efforts in this market appear to have been a failure -- at least so far. I think this makes for an interesting comparison with Apple's efforts in the handheld computing market, the iPhone and iPod touch. They aren't precisely comparable products of course, but it seems to me that Apple is succeeding where Microsoft has not, by taking a very different approach to the problem of handheld computing. So, based on what we've seen to date, who's solution to mobile computing is likely to succeed in the long run, Apple's or Microsoft's?
