I'll show this to people that said me before that I'm crazy because I always say that Windows Vista is better than Windows XP in the appropiate hardware, so they can shut up their mouths.
Windows XP is pretty obsolete to use in new hardware, but if you have an oldie Pentium 4, Windows XP (compared to Vista) is better. But some people can't still say to other people that are mad just for saying that Windows Vista is better in some ocassions than XP.
I think that compare x86 with x64 editions is unaccurate, but still, nice comparison.
