Coming with 11.10, we seriously need a "downgrade" option in the update manager. This would solve so many people's problems without causing them all the hassle of backing up their files, then just reinstalling their files. This is a must.
Also, Ubuntu 11.10 should stay in Beta stage for a longer time, to give the developers time to adjust to the glitches and fix them. I think everyone here got a bit pissed seeing all the new glitches in 11.04! And if it is still too glitchy by the time it is supposed to be released, hold it back 3 weeks or so! Better safe than sorry!
Also, the Unity dock should have a theming option.
And finally, there needs to be a classic Ubuntu spinoff. A lot of people are going to miss the original Gnome 2 desktop environment, and a lot of people aren't going to want to accept these changes, so better safe than sorry with that one, too! Maybe this new spinoff can take small, yet gradual steps to Unity over the process of the project, merging back with Ubuntu after say.... 4 years? This will help Mark Shuttleworth achieve his plan of 200,000,000 users in 4 years, as it will appear to a larger, broader crowd.
