Goodbye XP

Microsoft has announced it will stop selling Windows XP from Jan 2008. They want everyone who buys a new PC from then on to move to Vista and existing users to upgrade. I wonder how long it will be before they stop looking after XP users? I will never buy a computer with Vista on or upgrade from XP. My next PC will be a Mac or a build with gentoo or Ubuntu or Debian on it. As soon as they stop supporting XP they will lose my custom forever. Judging by the response to Vista they might lose a few more customers too. If the stranglehold MS have on office PCs also starts to slip then maybe, just maybe the giant will start to wobble.
