ZDNet has an interesting take on lower than expected client revenue for Microsoft. Given the expected EOL for Windows XP, I don't find it very surprising that a noticeable fraction of people are considering going to a Mac rather than a Windows box with Vista. I need to replace my main computer at home before too long (it's a little over six years old and was not bleeding edge at the time), and (for the first time) I am seriously considering a Mac - either a MacBook (which would also replace a five-year-old laptop), or maybe a mini. The drives in my current box could easily be converted to externals, and I don't do much gaming any more.
I've been using Windows, and developing for it, since 1988 - so this is a significant change. But I like what I've seen from Apple, while Microsoft seems to be getting more and more clueless.
(And why isn't there a good generic icon for "Apple"?)
