The company that kicked off the netbook craze is reported to be working on a netbook that uses a phone plugged into the device for connectivity. ASUS is looking at the modular phone system by Modu to provide connectivity on an as-needed basis by popping the phone into a slot designed for that purpose. This method would allow owners to have mobile connectivity with a single data plan on the phone.

I think this is a very poor solution, but perhaps the only one we will get in the U.S., whereas in Spain it was announced that their leading mobile carrier will let you share your iPhone data plan with your iPad – no extra cost.
