Ubuntu with Gnome. Hate Unity.
Agreed. I actually run Fedora (and have since Core 1 in 2003). I’m in IT and have been running RH or Fedora since 1993 or so. I can understand why people don’t like it, based on some comments I have heard. However, I feel it’s the best distro out there. I’ve tried dozens of different ones, and keep coming back to Fedora.
I'm currently using Mint with KDE and like it. I agree with the OP that the "disable touchpad when mouse connected" feature is pretty neat. I set up my wife's laptop to dual boot and this one little feature is one of the main reasons she now does most of her stuff on the laptop in Linux. Without it, the laptop is just about unusable for typing anything in due to the size and placement of the touchpad.
