-1retrig: Linux has top notch web browsers, office software, IDEs, graphics software, anything most people use a computer for, etc... I'm not sure what awesome and noble tasks you found Linux unsuitable for, but it's possible you just didn't put any effort into learning a new piece of software.
..back on topic:
10.10 was the best release ever, 11.04 makes some improvements, but overall, Unity seems like a 2nd rate version of gnome-shell. The launcher is cool, but I wouldn't say it's better than something like cairo-dock, which has been available forever.
Hopefully they continue to improve Unity for 11.10, when they begin using gnome3 instead of gnome2.3 as the base for Unity.
