I love Unity. It's the best Linux desktop I've had. I've used Linux on my desktop since '95, and Unity is the first Linux desktop UI that I feel is as snappy and productive as my Amiga used to be (yes, seriously)...

I felt that way at first, but I'm pretty happy with it now. The 12.04.1 stuff seems solid to me, and now that I'm comfortable with the new interface, I like it fine.

If their goal was to provide something that novices could get comfortable with quickly, I think they did a good job. It fell down for me in making the transition easy for people comfortable with the old UI, but that's clearly an audience they didn't intend to address, so I'm willing to cut them some slack.

It was a little rough at first, but it has smoothed out. I like it.
