If the APU on the Deck was user replaceable, that would open up a whole new window for upgradeability. But at least external GPUs work with it, bottleneck and all.,(reply>), The deck's APU is a mobile processor, though--I don't think I've seen a single laptop with a non-embedded CPU in like a decade. And I really don't think they could switch to a desktop APU--the 5600G has a TDP of <b>65 watts</b>--that's gonna deplete your battery in minutes, assuming it doesn't melt itself first.
