I haven't actually tried cPanel 11 however I just ran a test on one of my Dormant Servers and can see it's much better in terms of WHM.

cPanel never bothered me because I rarely used the thing however if I was coming from a fresh person to Web Hosting I can see it's a much better interface.

I have to admit still I'm not too keen on the "fatter" logos. I think it looks completely unattractive.
