Heck, I'd love to not even carry the GPU unless I want to use it. What ever happened to external GPUs for mobile gaming? I faintly remember hearing about them years ago, but I don't know if there were ever practical consumer/prosumer products. I imagine it's not uncommon for some laptop users to carry Thunderbolt docks that are pretty beefy (the one I use weighs a full pound, although I almost never carry it with me), and I would bet you could fit a decent mobile GPU in a similar or smaller form factor.
