Don't like Ubuntu Unity?
Use something else... that's the joy of the Linux world. Choice. Lots of choice. Don't like any of current distro's on offer? Create your own desktop environment. That's what Linux Mint, and a few others', did, basing their distro on Ubuntu; but you could just as easily roll your own distro using all the free and open-source software out there.
At the end of the day, it's all about choice and the freedom to innovate and push all of IT forward.
