I like iOS 7 in many ways, but it suffers from being WAY too bright, it's blinding. Also, the glass-like transparency is kinda obnoxious and does nothing but sucks up battery life.
Still, many things to like about iOS 7. I hope Apple opens up iBeacons to all other platforms. It's a cool concept, and it simply utilizes Bluetooth 4.0, so Apple could easily open it up. It combined with NFC could be a powerful combo. Sadly, the odds of Apple doing this? Slim to none.
Control Center is also something we need. It looks really nice, especially the quick launch apps (flashlight, compass, etc.). However, in whatever way Microsoft implements it, I do hope that, should they include the quick launch dock, they let us choose what's on it. A little customization can go a long way. I also hope, again, however they implement it, you can choose to only access it from the Start Screen. I don't want to be scrolling and u through apps, and constantly opening it up.
Overall, I think iOS 7 looks pretty decent, mostly because it borrows so heavily from Windows Phone. Every time I look at it, I kinda like it because it's reminiscent of Windows Phone. I just hate how bright and white it is, Microsoft is right about transparency being dead (distracts from the experience and kills battery), and the colors are obnoxious.
However, I can't believe Apple beat Microsoft to something MS came up with! I talk of course about closing apps. Apple took multitasking from WP, but they beat Microsoft to swiping to close apps. Why Microsoft didn't add this to WP baffled me, seeing as they had it first in Windows 8... Now if/when Microsoft adds it, they will be accused of stealing.
