I don't know what you consider outrageous, but you might look into the
Sony Vaio Picturebook. I use one of these for a moving map display for
both aviation and vehicular travel (with a USB GPS receiver). The PC
is about the size of a VHS videotape, and amazingly bright (can be
read in direct sunlight, though I wouldn't do so by choice). The model
I have is a Pentium 266 and runs Windows 98 - kinda obsolete, but does
what I want it to very well. The cables are a nuisance, but that is
also true of my portable aviation GPS. There is one offered right now
on eBay at a buy-it-now price of $399.
