to the OP question, Nope it won't, will still be nice option for someone who doesn't mind packing this extra kit for multiple cheap laptops... I guess this is the customer? would someone not just purchase a "gaming" laptop instead of this though?

Gaming laptops have weaker GPUs than desktop counterpart.

They'll work on anything with a CPU in time.

CPU power doesn't seem to be limiting game development.
