It seems to me that many phones will be pitched as computers, BYODKM. But I don't see any computers that you remove the bulky parts and it becomes a phone.

Maybe it is just perspective.

If my car can pickup the blue tooth signals from my phone in the house, I would imagine that I should have a computer that could do the same job as the phone.

Shouldn't it be easier to turn a computer into a phone than a phone into a computer?
