Ok, here's a naive techie question:
If the modem component is small enough to fit in an iPhone, why not put it back in the laptop as in the old days? Then wouldn't you just need a cord to connect it to a cell phone or land line? Or could it be wireless?
Maybe that spoils the elegant downsizing of the laptop or something?
I lied. There's more than one question...
This is not a "modem" in the sense of a thing you connect to a telephone cord; it's basically a wireless cell phone. Adding it to the computer would basically be the same thing as putting a cell phone inside the computer. It would be expensive, and it would not do anything unless you bought a cell phone plan for your computer.
