This is want I have been dreaming about. While sitting by the desk, I want to use desktop class CPU since there's no need to save power. However I don't want to drag a workstation class laptop while traveling.

I've tried having two different computers. Dropbox makes it easier, but still you have the problem that you need to maintain two separate systems.

I think technically this is not so far fetched. With the portable USB3 memory you could almost achieve it. This would just require that the operating system supports waking up in a bit different hardware (at least different CPU, possibly also different amount of RAM).



Isn't this the same as the gaming-oriented laptops that have offered external hot-pluggable docks for dedicated GPUs in the past?

Iirc there are even generic Thunderbolt based docks that could hook up some of the beefiest desktop GPUs to a laptop.

The CPU aspect is still an issue, but high end full voltage mobile CPUs are pretty powerful, and can still scale down power usage.
