On the contrary, I find that Unity is much more keyboard friendly than Gnome. Multitasking with the keyboard is very easy, just hold super and press the relevant number. I find that it is much more conducive to multitasking once I got used to it. Give it a fair shake. It's different, and I had some initial revulsion, but once you get over it, it can be one of the most pleasant desktop experiences you've ever had.
