I installed vista 4 days ago , and applied the latest updates with SP 1 . Also applied some tweaks . It has been a pleasant experience till now . running pretty smoothly . Somethings which run better than XP SP2 are : Photoshop loads faster . Winamp Bento Skin window doesn't stutter now when clicked on to show from minimized . It stuttered a lot in xp with the same system. And above all , vista looks sweet . Hard Drive Read Speed increased by 6Mb/s ( without the HDD speed tweak in vista, checked with HD Tune ) . Avg speed much more than it was in xp . Still have to get somethings ironed out. After that i think i'm going to keep this OS .
