Speaking from recent personal experience, I would rather have a slower release cycle that was less buggy than frequent headaches. It's almost like Firefox where you never actually realise what has changed.
To be fair it's essential that a web-browser is patched often and regularly, and ideally (assuming all the changes are under the hood and security fixes) then it's a good thing you can't tell what's changed.
In other news, Firefox 4's out soon. Whilst it looks good on Aero Glass, I don't know if I can get behind the style for XP.
