| With CoreAudio and the Build-In audio hardware @ 44100Hz with 16 samples buffer size we did measure a round-trip latency of about 2ms. Measured, not guessed. The only other hardware we found that is able to get 16 samples under CPU load is the Apogee Symphony, but you won't get better than the internal audio hardware.

For some time now, Windows using ASIO has provided users with millisecond-range latency. If by "dedicated hardware" you include a huge number of run-of-the mill PCI audio cards, then you are correct.
this is only true if by "millisecond range" you mean "several milliseconds" and if by latency you mean "playback latency" and by "provided users" you mean "provided users whose non-audio h/wand other software doesn't get in the way".
there's a large amount of varyingly-inaccurate, misleading info that circulates around regarding various kinds of latency on various general purpose OS's. i think its very important to be clear about all the caveats and details.
