I really didnt mind when phones were thicker. I'd be happy if my phone was thicker now if it meant having a bigger battery. I'd be even happier if my phone was thicker now and it meant I had a screen that's (optionally) twice as big in my pocket. Just some things off the top of my head that I'd like to have a bigger screen, but not carry around a tablet for: taking notes, maps in the car, gaming, netflix.
