Interesting.. I've been using the betas for a little while now, and have been extremely impressed with the stability. Seems to run well, startup and shutdown are
significantly faster.. although shutdown still isn't awesome, it's a lot better than Vista.
I would say I also
really like the new taskbar, and some of the new window features like "Aero Peek". It actually gives meaning to the little "preview thumbnail" that pops up when you hover over something on the taskbar in Vista. "Aero Peek" makes you realize how worthless that is in Vista, when now you can see the entire window instead of a thumbnail that you can't recognize what's on it anyways.
I am a little disappointed that, at least according to that page, you can't do the upgrade option from a beta to the RC. Not that you can't expect that when using pre-release software, it'd just be nice to not have the hassle.
And to make my post just a little bit longer, people should check out

As the new version has been recently released, 9.04. I dual-boot Windows and Ubuntu, and enjoy trying out the new versions.. and this one has been pretty good so far. A word of warning, though.. if your computer has ATI graphics installed and
isn't new within the last 6 months, I wouldn't bother. ATI made a crap move and put all of their graphics chips basically more than a year old under "legacy" support, which means no new drivers, which means no new drivers for the new version of Ubuntu. Although there is an open-source driver that works pretty darn well, it just needs more time (especially for people on laptops). For people with NVidia graphics, though, feel free to dive in.
