I was having a conversation about this the other day with a friend...We already have the largest feasible screen to allow the phone to fit in a pocket, we already have pretty much the fastest processors a li ion battery will allow (without either making the phone an inch thick and 3lbs or turning your cell phone into a landline that can be unplugged for short amounts of time if necessary), we already have text and voice input...
My question is: Whats next?
