Conversely, I see no reason for any device to support ALAC and not FLAC.
Isnt this implemented in silicon (or atleast implemented as some DSP-specific library) ? AFAIK that costs money.
Today, if you wanted a lossless player, that player had to have FLAC - which was taken from a commercial vendor like Tensilica [1]. But now that ALAC is an alternative, why would I even try to spend more money and also add FLAC ?
Plus, it is reasonably trivial to convert all FLAC to ALAC [2]
