Somewhere along technology adoption train, someone Microsoft Intel decided the world needed USB more than FireWire.

There, fixed it for you. They push motherboards and chipsets, hence by extension connection standards.

Also, USB is a lot easier to implement for a broad range of peripherals, from slow speed like mice to medium-speed stuff. You'll never see a FireWire mouse. Hence, if you only have one interface - and you want only one to shave costs - USB it is.

USB was designed for low-speed connections, which is why you see it used for mice. Firewire was designed only for high-speed connections.
