I just got my new HP HDX and surprisingly it has Vista 64 preinstalled on it (surprising because it didn't mention 64 bit anywhere in the description). I have a few questions regarding Vista 64.

Obviously all the drivers that came with it must be 64 bit but does all software I want to install on this have to be a 64 Bit version?

Or is it that 32 bit software will run as long as all drivers are 64 bit?

Will MS provide a 32 bit version if I request it?

Thanks!
Jamie
