If Android is so much better why aren't those users off enjoying their phones/tablets, instead of trolling here? A lot of posts I've read appear to be Apple haters having a cry at what iOS 7 doesn't have that other OS's have, and Apple is so far behind, blah blah blah.
As for the icons, this is only the first beta. There's plenty of time for Apple to act on the feedback and replace them if they have anything else to swap in for the current ones causing so much of a problem for some people.
Functionality wise, things are looking good, I'm looking forward to updating. So far my iPhone does what I want it to do, I don't feel I'm missing anything (quick reply would be nice but I'll get by without it).
I've been to the other side with Android, easy to use but I just didn't like it. Too much time wasted stuffing around with setup and settings, micromanaging battery usage, apps lacking the finish of the iOS equivalent, if I could find an equivalent. I had to root to make any decent use of things, so no better than an iphone without jailbreak IMO. Different launchers, keyboards, widgets and so on, all just gimmicks as far as I'm concerned. Not for others but that's why we are all different in our preferrences. Overall android wasn't a good enough experience for me to stick with it, I prefer iOS, for now.
But I'm not going to bang on about what I didn't like, nor am I going to claim iOS is the be all and end all and say anyonme not using it is a fool and must change etc. Use what suits you, don't waste your time bagging the competition, it just shows you aren't truly happy with your choice like you think you are.
