It's not exactly for everybody, but we have a sneaking suspicion that Sprint's new Sierra Wireless AirCard 402 mobile broadband card -- first spotted last month -- will make at least a few multiple laptop owners out there very, very happy. As you can see above, this one can function happily as an ExpressCard one moment and a PC Card the next, with each providing the same dual-band CDMA connectivity and support for EV-DO 1xRTT, Rev. 0, and Rev. A, along with all the other standard features and software you'd expect from a mobile broadband card. Perhaps the best news, however, is the price, which at $99.99 (after $180 instant savings and a $50 mail-in rebate), is pretty much in line with Sprint's other plan old ExpressCard options.
