Personally I hate the idea of Docks, and that is what Unity brings to the table. A dock... and a particularly annoying one. If you have to make a list of some programs at least make it so it doesn't get in the way. Gnome 2 and Windows do this by having a task bar of sort. Unity doesn't do this and every time my mouse gets to close to the edge is fudges up my work. When I first used it I kept on opening random applications which I had to later close. Also as much as I hate the dock, I hate to have my applications in extra large idiot proof touch friendly icons. I have a precession mouse and I want to use it to click on icons in a small list that has all my applications, organized but still small. Gnome 3 and Unity seem to assume that either you are blind, using a touch screen, or you can't point and click because the icons are fricken MASSIVE.
