XP is being supported longer now as billy boy has had to many businesses and big business screaming holy murder at him over vista, they gone back xp 64 quite a few of them.
The new windows 7 which is confirmed release 2010 or earlier if  nothing goes wrong, will bypass all the vista faults and will run with less memory, so gonna be funny those peeps that bought vista being told get xp 64 instead.
Will have to buy windows 7 as i will get windows 7 as their is no way on gods green earth i will ever touch vista, was quite funny 1 games player came in shop and said who wants by this vista crap from me.
1 bod said why and he goes its crap for heavy online gaming and i gone back to dual boot xp pro and xp 64, and its quite surprising how many games players have thrown vista out the window.
