- a little surprisingly, if you're on the iOS dev program, you'll also be good for OS X Yosemite, as well as iOS 8. I'm pleased about that, as the whole seamless iOS/OS X integration is something I've long wished for.
- upgrading was almost uneventful, save for the initial launch of Mail leaving me with an immobile progress bar for updating. Force-quitting it and relaunching brought Mail up immediately, so I suppose that's just its idea of a prank. =:/
- the typography is, as you'll have seen from the keynote, unified with iOS. It's a little odd, but I think I'll warm to it fairly readily. The WiFi icon could do with being heavier, to distinguish it from inactive/activating.
- no big problems on the iPad or iPhone thus far. Had the Preferences quit on the iPad on first launch, but hey, early beta.
- launching Xcode for the first time requires a few extra components, requiring iTunes to quit, which it seemed unwilling to go along with. (See above)
- iOS 8 installed on the iPhone and iPad uneventfully. Odd that iTunes can apparently only handle updating one device at a time, though. =:/
- annoyingly, the default on the iPad requires immediate entry of one's passcode to unlock. Worth resetting that to something lenient, if you're in a setting where it won't be abused. The iPhone required re-enabling of use of touch ID for unlocking, with the existing print data untouched.
- no devices have yet exploded.
As for the rest of the keynote.. well, that was a thing. =:D Really liking the whole "continuity" thing, which has seemed so obvious for such a long time. A new lower-level graphics API? That'll be interesting to follow. And a new language? If it can indeed provide the performance gains advertised, and do away with some of the more common programming banes, that'd only be a good thing. True, it's yet another language, but then again, I'm not really impacted, being currently on the C++11 team, with a distinct leaning toward the lower level side of things. (My, how marvellously uncomplicated Intel's ISA is!)
- as Byzantine as LJ's coding is, it's apparently reversed tack with Yosemite. Where previously OmniWeb 6's preview/post buttons didn't do anything, and only mainline Safari worked, now OW6 works fine, and Safari's dead in the water. I can live with that. ^_^;
