It's disheartening to see people just dismiss all of the issues with the IOS7 design.
It would be more useful to be constructive - point out specific examples of where the new design isn't working, suggest improvements, etc.
It is not constructive or mature to call everybody with a criticism a "troll".
It is also not helpful to sit back and say "oh, this will all be fixed by GM"; if you don't want to engage in the discussion, that's fine - you don't have to. From my experience with iOS betas (basically all of them), there are lots and lots of serious UI bugs that don't get fixed for ages even after GM - the repeat/shuffle icons are a good example. Sometimes people like to vent about niggly little things that annoy them (I know I certainly do!)
Discussion is good and healthy; nobody but the site's owners have the right to preclude discussion on this board. So please do not dismiss those with points to make.
For me the problem is in the way some people present it. To start a thread calling it junk doesn't seem very constructive to me. Especially using an example that clearly appears to be a bug and not a specific design choice. What would be more constructive is reporting these things to Apple. And since so many non developers seem to be running iOS 7 here its hard to know if legitimate complaints arw getting reported back to Apple or not.
In this case I think beta can be used as an excuse because Apple literally changed every pixel iOS 7 in a matter of 6-7 months. Some of the features might have been in the works (didn't make it in to iOS 6) but the UI certainly wasn't. Was Apple too ambitious trying to do all that in such a short amount of time? Perhaps. But obviously they were willing to take the risk of major change that isn't perfect but gets improved over time. That's why I've said I hope Apple iterates more frequently now instead of having to wait a whole year for changes.
