If you're the indecisive type, Verizon's newest data card is right up your alley, because you've got two different form factors at your disposal: ExpressCard/34 and
PC Card. The modem -- which hails from MiFi
-- has both PC and Mac compatibility out of the box, rocks EV-DO Rev. A (it fricking better), and most notably, includes a PC Card adapter so you can continue to provide your thirty-year-old 486-powered Toshiba Satellite with 3G on the road. It'll be available this Sunday for $99.99 on contract after rebates.
