MXM is alright for upgrading, but it's not modular the way this aims to be.
This includes cooling, so a small GPU could have smaller heatsinks and a beefy GPU could have huge heatsinks.
And if you don't want the GPU and the associated power draw plus the size and weight of the heatsinks, you can swap it for another module if you don't want to game on the go.
As they said in their presentation, it's not just for GPUs. You could have a supplemental battery. They will offer a storage expansion that gives you more M.2 slots. Hypothetically you could even just make a module that lets you fit a desktop GPU on the back, if you provided external power.
