I have to admit, with the inexpensive cost of LED displays, the availability of programs like Flash, and the miniaturization of technology (i.e. eBook Readers), I'm surprised no one has tried to be a real, working PADD (or, at least one with an animated display). With Adobe AIR, a Netbook, a touchscreen, and a little electronics knowledge, you could actually build a working, real PADD... with Okuda-display and all!
Imagine sitting down at Starbucks and pulling out your own little PADD to surf the web, read an eBook, or design your next prop project!
