You are correct, usually graphics and RAM can be used again when you upgrade. But:Frizzle said:Point taken on the 1 source for parts thing. That could be a problem. The fix would i guess put us back to how it is now.
As for the part exchange. Only the actual electrical parts change (leaving USB type ports aside for a minute) as opposed to something that moves etc. When the architecture changes, that usually only changes one part - such as the motherboard- unless i'm mistaken. You can still use the same RAM and GPU unless I grossly misunderstand electronics.
I think i could mentally iron out a lot of the problems in my head, though getting corporate people to do the same in reality might be a different story.
Don't get me wrong, I understand the insides are what makes up the console, but they're essentially the same as a family buying an HP pavillion PC, and then buying a new one every few years because it doesn't have the guts to run something they want. It kind of comes down to the console market catering to the hardware, and the PC market catering to the software.
- Graphics cards tend to be the first thing you would want to replace though, as the rate of improvement in that area is high.
- In ten years we have gone from DDR, to DDR2, to dual or triple channel DDR3. These standards have no compatibility between them.
- We are currently making the switch from SATA III to SATA III as an interface for consumer storage; not long ago it was IDE.
- PCE 3.0 is slated to appear within a year.
You could attempt to create an upgradeable console, but I think the downsides would outweigh the benefits.
Like you said, the people buying consoles are generally not interested in mucking around with the innards, and would rather just buy a new one when it comes out. I think it is probably the most elegant solution for consoles.
