Todd-
IR is cheaper and easier than R/C. R/C requires regulatory approval in many
places (like the US) and frequencies must vary with country. IR can be the same
everywhere and requires no approvals.
Of course IR has the disadvantage of being line of sight while radio does not.
Mass adoption of Bluetooth could make R/C very competitive economically in short
order.
