Now Canonical is at the stage (barely) where they are trying to figure out how you can make money off of a distro geared towards desktop users. Of course not a lot of people agree with their approach. When I found out how much data Canonical was collecting via Zeitgeist I damn near pissed myself. But it's my choice to either use regular Ubuntu or switch to something else. I switched to a bare stock version of G3 and it's OK.
That being said I am worried about the future of G3. I currently use it and it's pretty damn good. No, it's not a "tablet OS" whatever that means. No, the basic paradigm of desktop computing isn't ruined. In fact it's cleaner and far more cohesive than G2 ever was. The extensions cover about 90% of the gripes people have with the stock versions of it. Likewise, the kvetching about extensions breaking on upgrade seems to be well... stupid; you know what other programs do this? Firefox and probably a good number of other browsers as well. Drivers do as well. The easiest way to prevent that is to not use the bleeding edge versions of G3. Most of the popular extensions get upgraded usually around the time a newer version of G3 shows up on distro. It's really not a problem for end users.
Now with regards to Fedora I hope they keep the regular version of G3. G3 needs a platform to showcase their improvements and without it they are dead in the water.
