PC World: "At the risk of piling on, I'll join the chorus of those who wish Windows 7 Ultimate was, well, more ultimate--offering truly important features that aren't in other versions of the new OS. While I don't think having an "Ultimate" that really isn't will be the undoing of the House of Gates, I can tell you I won't be buying it.
I did, however, based on previous experience, purchase a copy of Windows Ultimate, because it was the upgrade for Windows XP Pro and required for the network I was running at the time. A business network I was running at home, mind you.
Having switched to a mix of Macs and PCs, I don't run that network anymore so Vista Ultimate doesn't get me anything and when I upgrade to Win7 it will mostly be by doing clean installs--that is if I upgrade my XP machines at all, which is becoming more and more doubtful."
