Yes, having tried unity as well, I've been somewhat disappointed by the launcher/menu, but I can see things improving on this front. I'll be interested to see what Wayland brings over traditional X, as well as continued improvements to the UI.

This scrollbar, while thin, actually expands to a standard width as you hover near or click on it. So basically just looks small to provide more usable screen space. I really like the concept, as it is a waste of 30pix to be constantly taken up on the right of the screen.

I like the diminutive menu borders, but I'm with you: resizing windows can be really annoying. They should do something similar to the menu, where the target is larger than the graphical representation on the screen.
