Is the 64-bit Windows 7 limited to a BootCamp partition, or can one install the 64-bit version on a virtual machine such as VMware Fusion 3?
Depends what you are going to run on Windows 7. Personally, I'd go 64-bit but if you have less than 4GB of RAM there's isn't much point.
i only have 2gb of ram
i'm just going to run basic applications like adobe photoshop, google earth, m word, firefox etc so 32 bit is fine? when would i need 64bit?
