Bingo.However, I've just built myself a nice little motorola lapdock system - it's a screen + keyboard & trackpad which can power a Pi via its internal batteries.
Under Â100 for the lapdock and cables - plus the cost of the Pi and other bits & pieces.
Similar there are some other smaller Android machines with USB, bit pricier than the Pi but come with a case, and better hardware which would be better suited to the task than a Pi.
Indeed - the crux here is the Pi's single USB interface. You'd nee a compatible USB wi-fi dongle - not really an issue, but something else you need. The Pi's USB is USB2, so 420Mb/sec, so fast enough, but USB is also half duplex (so is Wi-Fi), but that bus is shared between the Wi-Fi and on-board Ethernet.
Get a cheap old netbook and buy a new battery for it. Gordon
