"With good taste" is an important part of the equation. Not trying to force a tablet interface onto dual screen workstations. No, they'll have to do a lot better. Experimentation is fine too, but do it in an unstable branch.
It seems to me that Ubuntu won't really be stable until Canonical seriously tries to monetize and market it in cooperation with one or more hardware vendors for wide availability.
Until then, all Ubuntu users are essentially beta testers.
