doesnt vista require a massive hardware upgrade.
Its 64bit.... so you have to have a 64bit processor, and 512mb ram as i recall. But thats about it!
Erm...
All new versions are available for either 32-bit or 64-bit systems, depending on the needs of the customer.
Pretty much any current PC that can handle, will handle Vista. Most of the changes that are being bundled are cosmetic. All of the interesting Realtion Filesystem type stuff has been dropped !
