It's not what it looks like. We know, we know: it would seem that Engadget traveled all the way to Mobile World Congress only to get hands-on with a desktop phone, but fortunately for our pride, this device is quite the opposite. Though that earpiece would suggest otherwise, Invoxia's AudiOffice is actually just a speaker dock for your iPhone or iPad, meant to boost the audio quality when you're making VoIP or even regular cell phone calls. (You can also connect a non-iOS device using the built-in Bluetooth radio.) In particular, the company hopes the dock will appeal to small businesses forgoing land lines, though we could also see someone plugging a laptop into the USB port or adding a Bluetooth keyboard -- essentially, making the iPad the centerpiece of a more stationary setup. But is all that worth $299? Check out our hands-on photos and brief demo video and you be the judge.
