"I would argue everything we know about software engineering process says that more releases is better. Incrementalism lowers risk for engineers and for users. Once a year doesn't sound often enough to me, going the other way would just repeat Microsoft's failings." Yes, but that can be in the form of .X releases, not X. releases. Which is to say, by all means release X.2 and X.3 and ... X.9 and so on ... keep polishing ! But OSX releases 5.X and 6.X and ... 9.X ... and so on. Those aren't the actual numbers of course, but it is major releases that keep coming rather than minor releases.
