Yeah, we're starting to feel slightly bombarded with portable cellular routers, but we can't help but crack a smile each time one of these wonderful creations rolls into the commercial realm. Today, we've got Digi unveiling its new Digi Connect WAN 3G, which is hailed as an upgradeable 3G WWAN router for "primary and backup connectivity to remote sites and devices." Besides supporting both EV-DO and HSDPA standards, it also aims to provide "a fast and easy Ethernet-to-3G wireless connection" and even includes a built-in VPN. Sadly, no price is mentioned, but we're sure the folks at Digi wouldn't mind coughing up that information if you called up with the right tone of voice.
