Just because iPhone doesn't have a physical keyboard - doesn't make physical keyboards evil. Similar logic for trackball.

I have tried using physical keyboard on Blackberry and I felt pretty comfortable. I bet other manufacturers would come out with better physical keyboards. My flatmate has a Thinkpad with a trackball. Initially it was pretty tough to control it. Trackball and physical keyboard isn't bad just because I think it's bad.

So much from a Tumblr lead dev! I expected better.
