It's not the apps, it's the drivers. I've got expensive high quality audio hardware (RME Fireface 800) that doesn't have Linux drivers. Oh sure, I could invest $2000 to get a newer version, but that would just mean a steep learning curve to get drivers, hardware, and DAW working anywhere near as seamlessly as my Windows setup. It's not that I'm a Windows fan, I'm just looking for the most cost- and time-effective solutions. I'd rather spend my time recording and making music than sweating over driver and software issues.
