Windows 7 looks great
I installed the Windows 7 64bit on my home desktop two days ago and the system is running since then. Other than a HP LaserJet 1012 printer drivers problem and one BSOD, Windows 7 looks fine for Beta for sure. :)
Only one thing Microsoft should do, is, allow “free” upgrade for current (legit) Vista Ultimate version owners to Windows 7 Ultimate when the RTM is out.
I’ve yet to see a compelling reason why I need to buy Windows 7. The new TaskBar looks great but I’m not 100% up for that change.
