For the past two and half years I have been using Open Suse as my OS except for playing FPS games and / or while working with some .NET stuff. Unlike Vista, I heard good reviews from my colleagues about Windows 7 and thought of playing around with it using subscription license.

Windows 7 System Properties
So far my experience has been great and I very much liked the upgrade from Windows XP SP3 x86 32bit to Windows 7 x64 bit installation as I got 6GB RAM in my machine, Bondam, and XP capped me earlier with less than 4GB.

Windows 7 Experience Index Rating
Except for the Primary Disk with Windows 7, the Windows Experience Index Rating is comparably good. Hoping the ride will be smooth.
