it's cool that you use and apparently really appreciate Apple/Mac products. While high DPC latency can be an issue for audio and video work, there are hundreds of Windows machines (referencing notebookcheck.net DPC Latency Ratings) that have measured DPC latencies below 1000 μs (.001 sec) which is perfectly good for audio video work, and aside from Logic Pro, there are plenty of great DAWs that run very well on Windows platforms.but why? modern windows got a much inferiour low-latency implementation than a modern mac, like just everywhere. the whole 'dpc latency' problem is windows-specific
there's only one DAW, available on Windows, but not on a Mac, it's the Cakewalk. it could be justified, while it was free, but it's not the case anymore. Logic Pro is a terrific value for $199, all comparable options on Windows are much more expensive.
it's one thing to be an advocate, it's another to say your choice of platform is the only obvious choice.
