The Motion Computing M1300. It uses Intel's integrated graphics which has 16MB built in I believe and shares RAM proportionally with the amount installed.
Well, I don't know if that's true or not. All I know is that I go to properties and it says that Intel graphics chip shows 64MB of RAM.
I know of someone that soldered an ATI Radeon 9000 chip onto the mainboard in place of the integrated chip. It wasn't a true 9000, he just burned the 9000 instruction translation set onto a blank silicon chip. It gave the quality and features of the 9000, but it wasn't any faster.
