[VVertigo]

I'm probably pretty far out on the normal mobile user curve: my phone is primarily used for phone calls along with some texting and I don't even have a data plan.

I would suspect many mobile users would be faster than me (I know people who can go astonishingly fast), although I can (or at least used to be able to) type much faster on the BB keyboard than my phone screen. I am a decent typist though, so for most communication over a sentence I will resort to email using a desktop or laptop. I hate typing on laptop keyboards though and use an external one. I'm also not a fan of a bunch of back and forth texting, so for conversations like that it's usually better resolved with a call.
