thanks ...you saved me making a call to my local software guru. I'm about to buy an 15-16in pro-level laptop replacement of my 4 yr old microtower using Win XP. Nowadays, after retiring and doing photo fulltime, I'm now considered a heavy user. I'm a 'working' photog w/ Adobe Photoshop and potentially placing a max demand of 400 Meg of RAM and with tpical every-day demand of from 12 - 50 Meg. I originally thought when I purchase this new laptop about loading WinXP Pro instead of Win 7 Premium or Pro, 64-bit .
Now, I'll definitely use Win 7 Pro., but I wonder of what use the Win 7 Ultimate version would be to me (prob'y mucho overkill).
