Microsoft is removing Windows XP Pro from the distribution channel from tomorrow (1st July 2008), so if you've got a lot invested in Windows software that won't run under Vista, and are thinking about building a new PC in the future, you might want to grab an OEM copy while you still can. Google is your friend here, shop around and you can find a copy for £60. Obviously it won't be banned from sale tomorrow, but stocks won't be replaced once they run out.
Of course, you'll still be able to buy Vista Business or Ultimate (but not Home or Home Premium...) with a 'downgrade' option after today, but who needs the hassle? See this site for full details...
