I really want to like Ubuntu, but then I start it up and see horrible fonts, icons that look out of place with this new theme, and UI strangeness that doesn't seem to be justified. Why doesn't the close button sit on a corner? Why is the program launcher on a different bar than the already running programs? If I want to bring up a program like Firefox, I don't really care if it running or not I want to go to the same area to bring it up. I know I can change all of this things, but I have better ways to spend my time. Older users even if they wanted to aren't going to be able to change these things.
