Ok, so they just re-branded Novatel’s XV620. At least they picked a really good EV-DO card to re-brand though, right? The Dell Wireless 5700 Mobile Broadband ExpressCard will be available by the end of this week, and will be sold via Dell’s website (like everything else). ExpressCards, for those who are unaware, are the successors to the commonplace CardBus slots found on most laptops today. The ExpressCard technology allows for faster data connections (ExpressCards can use either USB 2.0 or PCI-Express, depending on what the developer chooses) and have a smaller form factor.
