I like the idea, the biggest benefit is of course the "all in one" deal - seems a waste to have to tether your phone to your laptop, or get a laptop with a SIM slot (and all the costs that go with it)

I'd like to see: 1. The source code 2. Support for newer devices (might go hand in hand with 1) 3. Support for wireless HDMI adapters, having to carry no cables at all would be very neat, although I guess this needs a power supply to last for any useful amount of time
