Irvine could learn something from Scottsdale, maybe. The SLX group stated a goal for upcoming V8 release to be be ""bug free."" Of course, there are caveats, but I think they mean it. It's release to Beta has been delayed over 6 weeks, probably because of that. (One reason for this goal, is that there are a lot of confirmed bugs that just never seem to get fixed.)
SLX's quality issues have been all over the map, but the past few years pretty good. Part of it is that when something goes bad in that app, it goes very bad, so a HF is pushed out pretty quickly.
But then, SLX has a different attitude toward publicizing bugs: it now has has a site where you can search on all bugs, open or closed. It tells you their status and planned fix date. Not perfect, but far better than my experience with Irvine.
