What's funny is that Apple seems to have found the anti-sweetspot for its release cycles. For example, for an app like Safari, it would make so much more sense to release very frequently (ala Chrome/Firefox) separate from the yearly OS cycles. Instead, new web standards features/JS improvements/what-have-you are inexplicably tied to fluff features like 3d tabs. On the other hand, features that would make more sense to not mutate constantly on your user get changed way too frequently (for example Mail, which quite frankly doesn't need constant updating, yet still broke Gmail for so many people on Mavericks release and should have really been caught beforehand). This strikes a balance that lacks the benefits of continuous deployment AND slow sober releases.
