Today, Microsoft ended support for Windows98, WindowsME and WindowsXP Service Pack 1.
I sure hope that they're more confident in Vista than everyone else seems to be. Leaving support for only one consumer OS seems rather risky. I can see finally eliminating support for Win98, and I'm surprised they even acknowledge that they created WinME, but I'm sure there are a lot of XP users who never upgraded to SP2.
Oh well, if it does backfire, it'll just Linux better…hopefully!
