It's not exactly a mystery as to which US carrier would be interested in picking up an HSDPA ExpressCard, but now that we're finally starting to see these 3G devices announced
(by Novatel, anyway), our appetites are whetted and we're sitting on our hands awaiting carrier announcements. Novatel's Merlin XU870, when snagged by Cingular (or T-Mobile Europe, or Vodafone
, etc.) will serve as your basic tri-band HSDPA / UMTS / EDGE / GPRS device capable of 3.6mbps speeds out of the box, and future upgradeable to 7.2mbps (via software update as new HSDPA revisions roll out). In other words, please get us a few of these immediately, thanks.
