Since computer subsystems (graphics, sound, netwoking...etc..) became commodities
You mean peripherals,add-in cards, and expansion slots.
Im referring to bus interface topologies, udma, hypertransport, rapid-I/O, full and half duplexing ...et al
As long as you have commodity expansion ports and storage interfaces, that support mass-market hardware&software standards, the rest of the machine can be proprietary.
imho, I think computers,following the mass-commodity cycle, will be more like fast food in the future.
You buy fries for example, eat them, then do you go back around and have the vendor refill your fry container with newer, warmer,better fries? no, you just order more fries, and discard/recycle the old fry container.
