If the cellular models of the iPad (full size and mini) have a SIM card and technically a phone number (for AT&T's connectivity sake, as it shows on my bill), then why can't we just have the phone capability on the iPad? Granted we would have a bunch of idiots holding huge iPads up to their head, but realistically it could be made to work only in speakerphone or by bluetooth. I don't like holding my iPhone up to my head and mostly only use a bluetooth headset or BT in the car. I guess the other argument is that you are not always going to want to carry an iPad since it does not fit in your pocket. Ok those points aside, I'm wondering if at some point we will be able to be device independent, like the way iMessage is able to contact us through our iPad, iPhone or Mac. If we could link our mobile number to our iMessage account and be accessed via any device, then we could switch easily between our iPhone or iPad to accept incoming calls. I'm sure that I'm not the only person to think this.
