Software vendors have the resposibility to their users to perform regression tests as part of their product. If Ubuntu doesn't want do do that, or do it better, then they shouln't bother to compete with other OSs that do.
I'm saying this after 10+ years of use of Linux on my desktop. The 8.10 issue (after deliberately picking low-powered OSS-driven hardware) made me move to OS X, which I hate, in order to have a continuously working desktop.
