But at least it prevented one moron from buying it, right?
Running WinCE on the empeg would primarily be a waste of time. Might as well run GPS on a CE handheld. The benefits of CE come with a complete mature product designed around it and its feature set. The empeg has enough processing power, but what could you do that you can't already do with linux? Pretty much nothing. One major thing you're missing is a nice large bitmap display.
I think you might have a hard time getting it off the ground anyway. Plus actually getting the applications to run properly - certainly if you wanted them to run on the current display. You'd have something along the lines of the AutoPC, but without all the interface buttons and more than likely some specialized hardware (including flash slots). Plus all the work of porting the player application... Ugh.
