Gobi

Gobi is about to make a dent in the wwan world.  What is it?

"Gobi is the mobile broadband technology that connects your laptop to the Internet via 3G cellular networks around the world.

Gobi is the first built-in, 3G modem with the ability to connect you to both EVDO and HSPA cellular networks using a single embedded device."

Instead of choosing a laptop because the module inside

is with Sprint, AT&T, Verizon, etc; choose one with 

Gobi and then decide which provider to activate with.
