I have to reluctantly agree with this statement. It shouldn't be that when I upgrade to 8.10 from 8.04 I am stuck fixing all of the issues that the upgrade itself broke (for example wireless is working poorly and is non-functional after suspends). While these issues are marginal and will only suck up a few minutes of my time, there are plenty of positives. Notably, GIMP, GNOME, and various other upgrades are quite nice.
I always felt guilty complaining about the stability of an Ubuntu distro. If I wanted stability I would stick with Debian or BSD. For free software of such quality, what I am gaining is certainly worth the time ensuring it works on my system.
