The speed of XP seemed the same and the OS seemed the same, but i liked the way in processes it identifies 32bit apps/64bit apps.
I would of used it longer but my *cough* didn't make it my own...
As for Server 2003 64bit edition, the whole thing seemed to just gel and mould at my finger tips, stability seemed more prominent and i really enjoyed playing with it. Overall i would say it only makes the 32bit seem faster, but i also found i didnt have to run everything in compatibility mode like i had to on the 32bit one, and also drivers JUST worked.
I LOVE IT!
