What Is Google's New "Next Generation Personal Communication Device"?

Google is, apparently, developing a new music streaming service. But new reports suggest that it is also simultaneously trialling a "next generation personal communication device" with its employees.

According to FCC applications cited by Engadget, Google wants to evaluate the "the throughput and stability of the home Wi-Fi networks that will support the device," as well as its Bluetooth performance, in the real world. Further details are limited, but the testing period should run until July 15th of this year.

Which all, of course, begs the question: what the hell is it? It doesn't sound like a new phone, and it's very tempting to assume that it might be a tie-in with the new media streaming system. Could it be Google's first tablet, which Schmidt speculated about last year? And one that's firmly focused on multimedia at that? Let's see. [FCC applications via Engadget]
