think the 64bit and 32bit is down to the pearson pc
I check my system and printer and scanner drivers are built in to vista and rest drivers i have check and they have 64 bit now oor said they be out on 30th when vista gos live..
there few Apps that are comming out 64bit that i wont to use auto cad etc etc
few games are comming out 64 bit too
So for me 64 bit vista is the choice for me
but if your thinking 64 bit then check hardware first then decide what your doing but it should be far more easy then xp64 because if they make 32 bit drivers they have to make 64 bit drivers to.I would say microsoft are doing this because the next big OS is said to be 64 bit only and this give ppl time to move over to 64 bit instead of just cuting of 32bit support
