Maybe it is. I feel like this is the narrative on every second cycle since 10.6 (Snow Leopard, to 10.5's Leopard), that "this" is the one where things get more reliable and nature.

They used to do this with even/odd releases - one doing features, one doing bugs, but I am uncertain if they do that any more.

Things SHOULD be getting more reliable if they just keep retiring older machines :)
