Quite honestly, i prefer to keep the phone part out of the tablet and just use a cheap cellphone to complement. there are situations, where I wouldn't want to take the much bigger tablet out to answer a phone, or take it with me for that matter. If I go to the mall, i won't be using it so the phone will suffice. Sometimes its plainly dangerous, like answering in some buses within my city (they would take it from in a second), or taking it to places where it could get wet ot dirty.
BTW, calling Benson an idiot and a troll is quite uncalled for. I know that he has always been helping people around here, and using good manners, so please don't make this forums an unpleasant one to roam. If you don't agree with what he says please use arguments against his arguments and not against his person. Even if you think he was being "trollish", aswering in the same matter only looks childish.
