As for those that are intend on sticking with XP, what re you going to do when updates cease?
I only upgrade OS's when a software application I want or need requires it. I have software that requires DOS, and Microsoft's lack of support has been a non-issue. I have a copy of XP Pro that doesn't need key registration, so I use that when appropriate. If Win 7 turns out the be the disaster that Vista has been, my next OS will be to Linux, and windows applications will run through emulator software. This is MS's last chance, so far as I'm concerned.
