John Gruber with the best round up of the huge App Store changes which were announced on Wednesday. Subscription pricing is now available in all categories (although not for all apps). Faster app review is not a coincidence, and most apps will now be reviewed in 24-48 hours. Then the controversial one, paid search results, which I hope is coming alongside better organic search as well.
We've repeatedly asked Apple for major changes to the App Store, and here they are. They may not all be what you were individually looking for but this is evidence that big changes can happen, and that can only be a good thing.
Ben Sandofsky with a fantastic article on the challenges and possible solutions around bringing UIKit to the Mac. I agree that this could be the year when we start to see this happen.
The sky isn't falling, AppKit isn't going anywhere and OS X isn't going to become iOS just yet, but this would be a way to start bringing the platforms closer together. If it happens, it'll be the start of a painful transition. But if you look 5+ years down the line, can you really see the Mac and iOS devices still running two operating systems that differ as much as they do now?
