A bit of both. It's a massive redesign, not all of it is well executed, and there's substantial performance degradation in some parts. There are also a larger than usual number of major bugs that shipped with the final. None of it is the-sky-is-falling material though. There are some bugs that will drive devs up the wall (especially when they end up getting fixed later and break the workarounds), and the lack of optimization in some components will put limits on their use, but nothing particularly game-ending. In summary: not a disaster, but less polished in general than previous iOS releases at this stage. Side note: I noticed this time that there was a lot less Apple engineer engagement on the dev forums. Couple that with the number of polish bugs (see: the Sloppy UI blog from yesterday) and you'd get the impression that the iOS team was stretched severely to get this out the door. Hope they're all getting some much-needed downtime.
