The only good thing about a Vista Business OEM license is that it allows you to downgrade to XP Pro . My advice for the people in my department is that unless they really have a good reason, get XP. And if they think they have a good reason, let me beat it out of them first. The few vista machines we have in the department are consistently far more of a nuissance to make work properly than the XP machines.

And as far as Vista 32/64, basically, if you're at all not sure, then you almost certainly don't want the 64 bit version. It's just too hard to find drivers for the 64 bit version (even for XP for that matter). What stunned me the other day was that they actually even made a 64 bit home version, which I just don't understand. It's even more frustrating when someone comes up to you with a laptop they bought with 1G of ram and it has a 64 bit home vista on it. That just shouldn't even be allowed to be sold. (In that particular case, not only could we not install some printers, but we can't install the vpn software he needed either.)
