On board video is not an issue. Laptops are a problem because of power saving techniques they use to save battery power. This affects the way the signals are sent to parallel port, and they have a lot of "sleep" type timeouts that affect whether hardware is ready when you need it. Board level computers should not have this issue. I bought an Intel Atom all-in-one computer to use with MACH3 myself, but have not had the time to build it up yet.
