I love linux and it's my primary OS. Been using Mint for over a year now and it's been great. I was somewhat intrigued about the beta and decided to give it a shot last night. Unity is a disaster. Even for a beta. Navigation and usability are horrible, the inability to move the main menu bar sucks for righties (lefties win this battle) and while I COMPLETELY understand it's a beta, my i5, 6Gb ram, intel SSD and intel HD video card are pretty freaking standard, it was crashalicious constantly. Never mind the fact that finding apps/settings is like nothing I've ever witnessed in Windows, OS X or linux..painful.
Reformatted back to Mint and am once again a satisfied linux user.. Canonical need to get it's sh!t together asap. In it's present form, it's a big steaming pile of crap.
