I'm not too sure what to look for but I need the smallest possible system that can give me access to serial port devices, even if it must use a USB to serial adapter. As far as I can see, PDA's are a no go and tablets aren't all that small. The device is to be used in-car for reprogramming engine and transmission parameters on the fly and be cable of this communication through an application that must work on the operating system (Windows-based, 9x and up compatibility).
So what are my choices if any, other than an overly large laptop?
