make it special

They need to lock themselves in with nvidia for GPU's and then like you suggest upgradeable cards, but only nvidia cards would work in the system.

The problem here is patent and copyright related. We would have a one-computer does all type device BUT the driving forces won't have it that way. It does not make good profit.

I'm sure this is another way for them to network with companies like microsoft to embed security features in their console to prevent hacking and pirating.
