Interesting look at Ubuntu vs Windows 8.

But as a desktop OS, Windows 8 got a universal thumbs down from our testers. They didn’t like being forced to use an OS designed primarily for touchscreen devices with limited real estate, such as a tablet or phone, on their multi-core desktops with wide-screen FullHD displays. Ubuntu’s Unity had pretty much the same criticisms in its early incarnations, but they have evolved since. In fact, much to our surprise, existing Ubuntu users had a much smoother experience with Windows 8 than existing Windows users!
