I'm quite happy that I have Windows Vista Ultimate 64-bit on my laptop with 4 GBs of RAM. With Ultimate on a 64-bit processor(s; I have 2 processors of 64-bit), you can upgrade your PC to nearly 128 GBs of RAM. Yes, one-hundred and twenty-eight gigabytes of RAM.
I wonder if you have to purchase the 'upgrade' to Windows 7 Ultimate separately...should have something that converts your current OS to the Windows 7 OS relating to your previous one. Such as me having Ultimate already, I could upgrade to Windows 7 Ultimate without buying the expensive version...
