  Incidentally, I'm typing this out on a tablet, that is able to access the internet, while at the same time, send music to my bluetooth headphones, and also use its GPS radio to pinpoint my locations. It can also take pictures, record sound, allows me to play games, edit documents, and any number of other things.  How many radio stations or TV stations does your tablet receive that don't come through its wireless connection to the internet? How much of anything not in its immediate vicinity can it access by any means other than its wireless modem?  ("GPS" in most tablets is a function of the wireless/cell tower triangulations instead of actually listening to the global positioning satellites.)  I've never said that multi-mode devices aren't possible, only that we haven't seen any.  <More later>
