This is not an easy question, but one perspective is to consider the impact on battery life. Running sbc encoding on a phone will have a greater impact on battery life than it does to run it on a laptop. The ideal is to have portable devices mitigate this with dsp hardware, but we can't count on the hardware or the driver to be there in all cases.
