Why doesn’t someone make a laptop with dual video cards on it?
That way you can run two displays in addition to your laptop instead of one.

It wouldn’t have to be able to run a 2560 x 1600 display on both cards, 1920 x 1080 will do (that’s two nice 24″ displays). I know lots of developers who’d pay good money for that.

PS: As with all ideas posted on this blog, feel free to take them and use as your own.
Whether you’re successful or not, it’d be awesome if you’d write back and let me know 😀
