I find myself doing a lot of quick text message replies and off the hip email checking with just one hand with my thumb doing most of the driving. It's just a lot harder to do with a 4.5" phone than my 3.5" one. I can live with it, but I guess it's to the point where I ask "why compromise?" and just go all in on the jumbo-tron.![]()
I still use Swype specifically for this reason. I can't really type one handed with anything else as easily.
