Re: Perhaps
Cool project but why not use an existing 'smart' phone and take the SIM out, and use WiFi hotspot with laptop for connectivity. Root the thing and put an 'open' firmware on it. I know that isn't as nice as making your own pocket computer but for most people it would be easy to do and you get the benefit of the hardware integration. Totally get that there would be security considerations when compared to building it from the ground up yourself.
