I updated to iOS 5 recently and while I like the new additions, there are some things that IMO they ruined in iOS 5. For example, Why is a blue frame around thumbnails in the Photos app now? iOS 4 used to have a very neutral gray frame. The Notes' font has been ruined, I think Noteworthy is what I used in iOS 4, it's terrible now. The "Slide the view/read" in the notifications is misaligned, the text should be lowered. I hate that Safari addressbar fade in. They've added a scrubbing note to the YouTube app when you seek but now it seems it's harder to tap on that seeking dot. They've also added a store button in the Music app, frankly, I don't need it at all there.
