Blah..Blah..Ubuntu 11.10 is out. You should probably have a look.
I'm definitely going to do my usual review when i get it working.
The half-baked mulatto excuse of a Distro keeps freezing up on me. It's all this damned Compiz crap. I have pretty FOSS friendly hardware as well....
Long story short: If you want a drop-in OS to do all the normal stuff, stick with win7. Ubuntu has nothing to offer you. Generally Linux doesn't either. Windows is now acceptable stable and secure. Better yet, buy a Mac.
If you want to use Linux (for the hell of it, for the software, for the rock-solid stability) use a better Distro. Mint, Fedora (maybe), openSUSE...I personally like Arch, but it's a little intimidating at first.
I say this as dedicated Linux guy.
