Well, motherboards are fairly easily replaced in PCs just like most other parts. I'm just saying that releasing new versions of consoles every year or so is insane. The reason consoles exist is also to give people a system they can work with for at least a few years without having to replace it constantly.
I don't think making consoles moddable would go against the point of consoles. The reason consoles exist is mainly for budget reasons. Sure, they also exist so you can get the full package in one go... but that doesn't mean modding consoles has to be a difficult affair. As long as they use parts that work together well and are suitable to replace old parts with, there should be no problem. And it's certainly preferable to needing to buy a new console every year. Imagine if people with PCs needed to buy a new PC each year - i.e. pay for parts they don't need! It's no different with consoles: you're paying for things you don't need because you already had them (a perfectly fine processor, motherboard, etc).
So unless you've got a better idea, I say either make consoles moddable or do away with them completely. But don't make people buy a new one for like 300 euros (if not more) each year.
