This will be pretty much what you get after it has been verified by Nokia and the carriers, as it's gone 'gold'. Runs like a dream on the 520 here. Haven't heard any problems so far while browsing through /r/windowsphone even.
Camera works great, WhatsApp better than before and IE runs sweeet on mobile data (it's llightning fast btw!). This is NOT the case for everyone. I did see a few people talk about it, but most of those also had those problems on 8 from what I've seen. I honestly won't worry about it. It's so much better that it's just a no-brainer. And nothing a soft reset can't fix.
not trolling, simply dont follow apple at all; is that what a new iphone looks like? (software, not hardware). looks stunning imho, still an android guy, but i might be looking for a mock of that shortly..
