Good point! My experience was XP to Windows 7 Pro 64-bit. Word on the street is that Windows 7 64-bit is faster than Windows 7 32-bit when working in Photoshop, but I have not personally tested it between the two. Like I said, I’m sure the casual user would not need the 64-bit. I could have lived without it, but the IT person who recommended it to me knows the type of work I do, so thought the 64-bit would be better for my particular circumstance. I have been happy with it except for the fact that I can’t use my SanDisk Cruzer 8GB and some of my Compact Flash readers…
I bought a new machine with Windows 7 Pro 64-bit installed, so no upgrade.
