The N7 is a great on-the-road device. I mostly leave my network in the backpack these days and just use the tablet. It does video chat (Google Talk) perfectly. I haven't tried Skype, but I do use Skype on the larger Xoom. I use Skype less and less now because of instability, dropped calls and laggy presence notification. I generally use Skype only if the other end can't use Google Talk, which is getting pretty rare.
I also ssh from my Android devices to various places. A Bluetooth keyboard makes this quite pleasant, and soon I will add a Bluetooth mouse. I will need to find some equivalent of the Xoom's portfolio case, which stands the tablet up in a laptop-like position. And much better apps for such things as code editing would be much appreciated. Free and open please. If nothing shows up soon I plan to improve my Java skills by writing something.
