Sorry for the snarky nit picking but...
One of the critiqued UIs includes the following annotation:
Rational Team Concert has home icon in top corner. Why?
Surely the author wouldn't be so indeterminate in their own design right?
Targetprocess 3 has a user gravatar in the top left corner. Why?
(Actually Targetprocess looks like it has a very nice UI, but then again I don't find the others all that horrendous either. There's just no accounting for taste.)
