Now that Sprint's XOHM service is officially live in downtown Baltimore (and working in cars, phew!), how's about taking a look at the card that's handling the magic? Samsung's SWC-E100 ExpressCard, which was conveniently leaked by Sprint early last month, is a "simple, inexpensive" card that does a more-than-adequate job at placing you on the mobile broadband superhighway. Reviewers at PC Mag dubbed it a "solid first effort from Samsung for getting laptops onto Sprint's fast XOHM WiMAX network," and while the card "worked as advertised," the inability to work with EV-DO or any non-WiMAX protocol was sort of a downer. Furthermore, the card won't play nice with OS X and there's no external antenna port, but they do bundle a potentially important extra: a PC Card slot adapter for users with aging laptops. Bottom line? Not too shabby for $59.99 sans contract.
