I'm only considering the 64 bit version, because it seems quite pointless to me to run 32 bit Vista when XP is just fine in 32 bits. I could perhaps run 32 bit Vista as a last resort , as I get Vista Business CD keys for free from my school's connection to MSDNAA.
Now, what are you ya'lls opinions? Is installing in 64 bits worth it (lack of driver support for some things, software support), and is 32 bits vista worth it since XP works well enough? How much faster is ReadyBoost to a system's responsiveness?
