Ah can not handle the truth can you. People type on average faster on physical keyboards over touch screen. No way around that. On a physical keyboard you can type by feel because you know when your finger is inbetween 2 keys. Can not do that on a touch screen. Or tell me how you know somthing was pressed with out the sound on the iPhone. Take away that click sound you would not know if a letter was not registered but on a physical keyboard you can tell that information by feel.
Please provide the data to back up this claim.
