WE need a mobile/portable that.. I am not up to speed on the latest technology but is there a mobile/portable that has: 1) a battery that can be swapped easily so that you can have a back-up battery always ready? 2) an input for a standard fullsize keyboard? 3) an input for a fullsize external monitor? 4) has root access available and capable of dual booting? basically Im looking for a mobile/portable that is capable or replacing a laptop or desktop. (and carputer, GPS, router, etc., etc.) I have this idea that Im sure others have also thought of too that we only need one device really.. plug your device into a monitor and keyboard at home or office (plus speakers and all other PC periphs) plug into car for all the stuff in the car.. stereo, gps, engine manegment, etc., etc. and also plug it into anything else you can think of. I know this is possible now but I havnt heard of it yet. what is the closest device that you know of to what I have described that is currently available?
