Sorry, but there is. That's exactly why data bus technology, protocols and driver layers exist. And as a crazy tangent, it's the same reason why the human species exists, but back on point. Data bus technology, protocols and driver layers, for obvious 3rd-party reasons, evolve much slower than the peripherals that connect to them. Some good examples are USB and TCP/IP.

I still own a working version of a very early (if not the earliest) 3Com 802.11b hub that all my WiFi devices could still connect to. That was 1995ish.

Please stop drinking the telecommunication industries' kool aid. The buses inside these small devices can handle the speeds, and the batteries are sufficient. The modular idea is sound and would promote much needed competition, it's the FCC and their overlords that are the problem. Europe doesn't seem to care because they've settled on GSM, but some of us Americans care.
