Back is the new blue ?
On a semi related topic, I've been trying to "downgrade" my Windows 7 prerelease which is a Windows "all included" version to Windows home (which I actually bought directly from Microsoft.
Except downgrading is not allowed. So I theoretically have to re-download all of my Steam games (which is what the Windows partition is for).
I'm still working on it (there are apparently hacks around this, some of which don't seem to work) but this is one of the many reasons that have kept me off Windows for the past 15 years (working with the MS people at the time and knowing a number of inside things was another...)
So I run Linux and it works for me (I also worked with the Apple people). I'd still like to be able to run my games and I'm really not into consoles, so unfortunately I still dedicate a disk to our evil overlords and spin it up every now and then.
