yup time to drop Ubuntu for another distro :-(
I tried it, still sthe same complaints AND I've had to use Windows 7 for an app I couldn't run on Linux.
Using Windows reminded me of the features missing since the Unity interface became the only option out of the box.
I've got a smart phone and a tablet. And I'm absolutely positive, because I don't use them for the same primary functions, that I don't benefit by having a touch centric UI on a device that doesn't use a touch interface.
Will my next primary content creation device have a touch interface? I don't know. Even if it does that won't resolve the shortcomings named in my original post.
