I mourn the loss of my keyboard. The iPhone is a content consumption device and a camera above all else.
While I like not having a physical keyboard, aside from text messages, I loathe typing anything of length on a smartphone.
I also find the UX of the iPhone's autocorrect to be really backward and frustrating; when I type a word, and I get a suggestion, I shouldn't have to lift my fingers from the keyboard to kill the suggestion. If I keep typing -- then keep what I am typing.
