Got an iOS device with a retina display? Turn it off.
The little spinning wheel that you see after you slide to power off has FINALLY, after two years, been updated for the retina display thanks to iOS 6.
It falls in line with what I've been thinking today and what other people have been saying- iOS 6 is all about polish. There are plenty of features that people wanted, expected to hear about today, and still won't have for at least another year. But I guess that wasn't the point- Apple simply chose to pretty up what they already have- revamped maps, improved Siri, more and deeper integration (notably, Facebook).
Something I do want to point out though- you mean I can tweet and post to Facebook from the notification center but I still can't reply to a text? What a tease...
