Having tested some clean installs of Windows 7, it really is a very smooth process (much improved over XP) -- at least for the somewhat technical user. I have not tested upgrading from XP to Windows 7, but it's probably not a good idea. Regarding the learning curve, most users will probably view Windows 7 as just an enhanced version of their old XP system. The taskbar and menus are still there and as long as they can find the big 'E' and "W" buttons in the taskbar they are fine. I don't think Windows 7 will have much of an impact on Mac sales either way. Most users that were tired of XP probably switched to a Mac (if they were able to choose).
