You're late to the party there. Computing power is now stupidly cheap, much cheaper than any of the mechanical devices you need to interface with it.

This was most dramatically run home to me by my first Raspberry Pi, which cost me less than any of the peripherals I connect it to. Admittedly this is because I like having decent keyboards etc., but the interface is the hard part of the computing experience. Things that move are harder to build well than a few highly integrated circuits.

So yes, our computers have been disposable for a while already. EC2 delivered the killer blow at the other end of the spectrum.
