I am guessing it must be something like this. Just slide the module in. They are talking disruptive, so the swappable part seems very likely. I can't imagine it could have an external antenna or it would be silly, and not disruptive at all - just a usb 3g modem in a small form factor. The way things go though I'd expect a proprietary port so that they can monetise the modules through licensing. Or perhaps Archos are the good guys.
