Former XP user who upgraded to Windows 7 here. I am hugely impressed with Windows 7 and the annoyances listed here are valid complaints, but on the whole extremely minor.<p>My big complaints are:
1. Upgrading from Windows XP to Windows 7 is a horrible experience if you made the mistake of buying an upgrade license.
2. Windows 7, presumably borrowing from Mac, does a lot more to hide details about errors from the user. Maybe this makes the computer less scary (questionable IMO, but at least arguable), but it /definitely/ makes it more frustrating to diagnose and fix problems.
