The entire "open source doesn't look as good" myth died a long time ago... at least 3 Ubuntu releases ago.
Better by far, certainly. The Ubuntu crowd has made significant strides in the past few years. But just look at the "Ubuntu One Music Store" image and tell me you don't see glaring inconsistencies in padding, form outlines, and control styles. Then look at other applications and notice which buttons are shaded and when, and resizable edge styles, and why does the shade get that dark near the bottom without a font highlight to counter the harder-to-read lower contrast?
Try comparing native/native or virtualized/virtualized. The vmware and virtualbox drivers lack many functions that are used in native-running ubuntu or windows, for that matter.
I hate trolls like you. A lot of us work really hard on making it the best damn platform ever, and it is, and then some quack who doesn't know anything says "it's just like Windows 95" which shows that they didn't even bother to try it out, or take the tour on ubuntu.com or even watch a recent video of the latest release on youtube. And that just sucks the fun out of life.
Please, actually take a look at it before saying something ridiculous.
Calling users trolls who don't know anything doesn't make me want to give you any credit. Vetinari made me consider that I might be missing out on the best the platform has to offer but you just made me want to uninstall it.
