Apple Developer Center is back online along with iOS 7 beta downloads

Macworld: "iOS 7’s new design is a stunning change to the iOS infrastructure, with layered looks and minimalistic icons. But for those of you thinking, 'Gee, I might pay $99 for that developer’s kit just to get a glimpse of that new OS interface,' we’d suggest holding off. Sure, it’s nice catching glimpses of iOS 7 in the Apple keynote, in briefings, and around WWDC parties. But a first beta is still just that: a first beta. We’ve enjoyed what we’ve seen of iOS 7, for sure. But we’ll enjoy it even more in the fall, when all the finishing touches have been made and the operating system is ready for primetime."

CNET: "As we said before, iOS 7 brings huge changes in the visual department, which is an important part of the way you relate with your tablet or phone. Yet the really substantial, game-changing new features are few and far between. That said, Apple has a history of keeping its most pulse-quickening news for its next iPhone and iPad announcements. For that, we will have to wait until this fall."

The Verge: "Apple is showing that it can adapt, borrow, and tweak ideas from the competition, that it can expand what iOS feels and looks like as well as what it can do. The problem now is that it seems to be buckling a bit under the weight of an end-to-end redesign. I'm hopeful that in the next few months, as Apple ramps up for the introduction of new hardware at its fall event, some of the design and functionality issues that have yet to be addressed will be nipped and tucked."
