I updated to ios7. What a disappointment as far as the music player app (the main thing I use it for). Bright white background with red text and dead flat (no 3D effect as in ios6). Much more scrolling required due to the way album/artist lists are now displayed. It looks unfinished as well, I just don't get it.
A complete strain on the eyes. Crazy bad. The previous music player app was perfection. I can understand a few tweaks but this is drastically different.
I'm not one to complain much, and I don't frequent any Apple boards so I'm not on a crusade to post all over the internet about it. But I thought it worth mentioning, if you are using a touch 5g for music only, maybe avoid updating as long as possible. I understand you can't go back.
Consider this a public service announcement, LOL.
