I was really scared by all the stuff I read about it, and switched back to XFCE, which I have used on and off since back in the day. I did some distro hopping, even though I've used Ubuntu since Warty, and I first tried Gnome Shell, since Gnome 2 was going away anyway. I tried really hard, but I just don't like Gnome Shell. Even adding extensions, it just doesn't feel right. I finally gave up and re-installed 11.04 on my laptop and dove into Unity, and I don't see what the big deal is. It doesn't seem like a tablet interface, it's just different. It got better in 11.10, and I'm happy. I'd like some tweaks to the Dash, but overall, it stays out of the way and lets me focus on whatever program I'm running.
