If you have a known constant output lag, a known constant input lag, but no lag in the monitor for just the track you're recording, it seems like the software has everything it needs to put back the performance exactly the way you recorded it (and to adjust the offset for the click).
Monitoring. To monitor sound wet (as opposed to dry direct monitoring) you need very low latencies. This becomes important if you apply non-trivial effects.
Okay you have reverb or chorus or anything else you must have the mix wet. If you don't you are throwing everything off. Once again if you are not recording multi-track it really doesn't matter that much. If you throwing multiple of tracks and multiple of recordings its a HUGE issue that just manually or automatically delaying tracks won't fix. If "any modern DAW" could fix with a latency compensation then no one would be writing and working on latency for 20 years.
My point latency doesn't really matter for most people recording. BUT if you get in that realm where you need to worry about it then its a PAIN no matter what your OS is. Apple isn't "superior" in audio recording just like it isn't in video and image manipulation. OS is more about people's feeling and attachment to their OS's company's marketing.
I think Apple has been dishonest and hostile to people so I don't like them as a company. You can't trust them not to throw the rug out from under your feet (Thunderbolt cost studios thousands and thousands of dollars). Lack of a new Mac Pro also is a HUGE issue for most video shops now. Their OS drives me nuts and really unreliable for me. Other people love it and I am fine with your opinion until they think everything else is garbage.

Am I missing something?
