Thanks Noel for the insight. Very informative!
The only software development model that I've seen successfully implement a continuous development "fix" cycle is Reaper. Of course it's a *completely* different model, with users performing a sort of beta testing service. Seems to work for very quick updates, but feature wise it seems much slower.
Seems like bottom line it's a resource issue and depends on what the focus needs to be - can't be everything at once. And nothing will be perfect for all users, etc
FWIW I've never had a "showstopper" bug (not that my experience is representative of all) In an any case, I think things (especially now) are much more robust. I actually *like* the annual-ish release cycle - as long as there is no major issues with overall quality.
