If you don't like Unity, you don't have to go to Linux Mint, or Debian, or Windows or a Mac.
KDE or XFCE are simple installs from inside Synaptic or the command-line. And unlike Unity and Gnome 3. They aren't filled with bugs. They actually work - and work well.
I've long been an Ubuntu user and fan. I'm terribly disappointed in this release. It's filled with bugs. And Unity is being forced as the user interface, instead of being offered as an option. Unity is a great tablet (or netbook) user interface. But I need a real desktop interface supporting multiple monitors with multiple virtual desktops. It appears Ubuntu is headed in a different direction. For now, I'll use Kubuntu (KDE). But if Canonical continues down this nonsensical path, I'll be finding another distro.
