For me i have installed Vista Ultimate on

Intel 1.8 Ghz
768 MB SDRAM
GE Force 6200
17" CDT Monitor

Windows Vista Ultimate

AMD Athlon64 3200+
MS-7184 Motherboard with ATI Xpress 200 graphics
512 MB DDR RAM
17 " CRT Monitor (COMPAQ 7540)

Home PC - Vista Ultimate
Laptop - Vista Bussines
Work PC - Vista Enterprise

Vista Ultimate on my test and main box, and the laptop for my wife. Vista Enterprise on one of my machines at work.

Edit: they're all x64.

I get Vista Business for free through MSDNAA from my university, so that's what I'm gonna move to after this term is over.

I got Vista Home Basic on my laptop, thats what it came with anyway. I put Ultimate on it shortly after all.

I got Business x64.

Home Premium for me!

I don't have Vista! And I don't want it, either! But if I did get it I would probably get Home Premium or maybe Business.
