Ryan Block takes copious pictures and tests the speed of the newish Verizon V640 ExpressCard EV-DO adapter over at Engadget Mobile (setup involved putting the card in and hitting 'OK'). If you haven't tried EV-DO, then you don't know what you're missing. It is basically wireless broadband (that is a horrible oversimplification, but do you expect anything less from me?) and if you live in an area with coverage it means you can be untethered and connected all at the same time. It is sweet, and a blogger's best friend.
*Verizon is currently in the process of acquiring AOL, Engadget's parent company. However, Engadget maintains full editorial control, and Verizon will have to pry it from our cold, dead hands.
