millzyI get the hassle of having to install Windows, then Sonar, but are there really performance issues? When you say 'underpowered', does running Windows on a Mac somehow downgrade the performance of the Mac? Sorry, still trying to understand apart from the hassle of installing another OS on the machine, what the Bootcamp issues are.
Well, for a start MacOS's Core Audio and Core MIDI mean there's no need to worry about setting up special configurations that disable cpu sleep modes, core parking, etc. to get consistent very low latency performance. That alone counts for a lot.
OS updates generally don't result in the kind of issues that see lots of threads on this and other forums. Updates aren't pushed or compulsory either.
If you need MIDI over wi-fi or a virtual MIDI cable they're built in to the OS and "just work". No problems using wifi or bluetooth at the same time as a DAW either. Good, native wireless MIDI networking is one reason you see Macs on stages rather than laptop PCs.
Another factor is the hardware consistency. Let's say my gigging MacBook died or was stolen. I could order a replacement and have it in 24 hours if bog standard, a few days if customised. And then be absolutely certain I can stream my backup image onto it in a few hours and it will work. There's no assurance that's the case with laptop PCs. I could even do fly gigs carrying just a USB drive or some DVDs, ask the promoter/venue to provide a Mac to the required spec and install my stuff onto it in a couple of hours or less.
Use the bootcamp drivers and you're running a Windows computer with all that entails, good and bad.
It's just a small snapshot I know, but I was at a small, quite unique and very informal festival over the weekend. "Small" in terms of audience capacity, but some very well known established bands in their fields (and in at least one case internationally for nearly 50 years). Every computer on stage, running the mix or lights/on-the-fly video projection had a glowing apple on the back of it. A few iPads as well. Not a single PC, and talking to people, both band members and musicians amongst the audience, I suspect that might be the case for some time.
What a large studio requires of a computer system and what a project studio or live work calls for are rather different things.
