T-Mobile web'n'walk USB modem

Towards the end of last year, we reviewed Vodafone's USB 3G modem. By contrast with other PC Card-based modems, this was a plug-and-play device that was simplicity itself to use, which was enough to earn it an Editors' Choice award. Not to be outdone, T-Mobile has launched a rival. As more notebooks begin to incorporate SIM card slots, the long-term value of separate modems may be limited. But if you don't have built-in SIM support, the plug-and-play approach has immediate appeal.
