I love my linux world. The only part which I would appreciate is more polish in the software. Most software has a great set of features but it seems that all these suites are always missing the last 5% of development (e.g. making the application feel very polished).
To me it seems that the only way we can fix the desktop is to throw money at it. The last 5% of development work is usually boring (finding and fixing all the corner cases, etc...). I think that the only true consumer ready desktop right now is Ubuntu (yes, with the Unity interface). It has become a very polished and stable package with a lot of focus (maybe a bit too much?) on the right things. Don't get me wrong, I am a huge KDE fan (I contributed code), but to me it seems that it is missing the last 5% of development work (e.g. Kwin crashes occasionally, the panel wont stick to the top and will sometimes be in the center of the screen, Kwin seems to be slower than compiz...).
Canonical has the resources to provide a really solid desktop experience (and it already does) for most average users. For the rest of us, there is still Arch, Mint, Fedora, etc which allows for more customization. The problem is, that most people want their machine to just "work" and not tinker with the OS to just get it perfect.
Good job Canonical!
