ok don't laugh at me lol
i am running windows vista ultimate sp1 on a:
intel celeron 2Ghz
1256mb ram
via chrome9 hc IGP integrated graphics with 256mb ram
the laptop cam with vista basic and it sucked really slow etc
when the sp1 came out i decided to give it another try with ultimate. i was really surprised. speed has been increased with more then 50% for me and i am even using the aero inteface. my laptop responds very wel and even converting a divx to dvd only takes about an hour.
i would recommend it to everyone who's running vista
