What I'm trying to do is gauge the level of interest in the form factor, not necessarily the technology inside. You could tackle the technology in a hundred different ways (console, PC, dedicated PCB, CRT, LCD, TV, etc.). What if this form factor of a device (high quality construction, table top playability) could play 5-10 games in a legal, licensed way? I know that this site isn't necessarily the best place to put aside the technology aspects of such a project (that's a large part of why we're all here in the first place, that this is just plain fun to build!), but from a consumer stand-point, I'm interested in seeing what the interest is.
To answer your question directly though, a laptop wouldn't be a good choice for production in any reasonable volume; very costly and difficult to work with. For a one-off unit though, it's great.
thanks,
