the biggest problem with this is that you end up with a solution no better than buying a 7" HU, for more money (case + parts + screen) which won't work as well as a HU (feel like waiting for your HU to boot up? what about OS issues? decent software to use on a small screen?). its not fun, i debated this (electronics nerd that i am
) and decided to just get a HU with a memory card slot.
it mostly comes down to, do i want the wank factor of having a pc in the car?
