Cloud Engines, Inc., makers of the Pogoplug line of devices and accompanying software, are launching a new hardware product today called Pogoplug Mobile. The device works like the company’s current Pogoplug product - you attach your hard drive or drives, plug it into your router and instantly have your own personal cloud.*In short, it’s like a NAS (network-attached storage) box for your home.But with the new Pogoplug Mobile, the system has been optimized for use with mobile devices. It’s more of a “mobile accessory,” says CEO Daniel Putterman. That’s why you’ll soon find it on the shelf next the Bluetooth headsets, and not hidden away in the hard drive aisle, he says.
