It may seem like a small thing to get annoyed over, but this, to me, is one of their worse changes and I'm not sure I want to upgrade to iOS 5 now. How long can you really go without updating...? :S
Seriously? You're not sure if you want to upgrade because you have to click 'music' when listening to audio and 'videos' when viewing video?
I can't say I think it's an awesome change, but one benefit is that the bottom icons in the music app now have an extra available...which means I can give podcasts their own dedicated button, which saves a step for me (going to the ...More button).
What a pouty statement. I'm taking my ball and going home...
