There is absolutely nothing about Apple machines that makes them inherently more suitable to audio work than a well built computer from any other source. People who are paying for over-priced computers from Apple are unlikely to think much about how much money they would save by buying Sonar instead of one of the already OSX-ready alternatives.
I've found myself having to get into using Logic over the last few months. Nothing to do with being unhappy with Sonar, entirely due to working with people who are heavily commited to Logic.
Anyway, I bought a new (well, refurbished by Apple) Macbook Pro three weeks ago. To get it set up to handle audio with a stable round trip latency of around 6ms I had to do.... Nothing. No digging into the BIOS to switch off various cpu power saving and speed stepping modes, no registry editing to switch of cpu parking, no killing of loads of services and background processes. Nothing. Just load the RME and MOTU drivers, update the UFX firmware and let core audio and core MIDI handle the rest. Wifi, that killer of real-time performance on a PC, no problem at all on the Macbook.
OK, there was one thing. I had to stop Time Machine backing up everything every hour.
And the Macbook, though being a quadcore i7, is much less powerful than the PC in my sig. Cost a lot more of course, and Apple do have their own peculiarities like no TRIM support for non-Apple branded SSDs, but many of the problems DAW beginners have with Windows PC DAWs simply aren't there with Macs.
As for saving money on the DAW software by buying Sonar rather than an OS X DAW, Sonar Platinum costs considerably more for a first-time buyer than Logic Pro X. Apple have the advantage of being able to use their software as a low-priced incentive to buy their hardware, then Apple make their money out of selling that hardware. The combination works together and if one half of it generates little or no income that doesn't matter so long as the other compensates.
Splat gives you more plugins of course and more soft-synths. Equally, Logic has its' own set of oddities and Sonar, in my opinion, wins out in some regards, while Logic compensates with some nice touches I'd welcome in Sonar.
All the modern DAWs that have been around a while are very capable and all have their odd behaviours and bugs as well. Ironically it's the "industry standard" one that's often been playing technological catch-up with the rest while Sonar, or Cubase, or Logic, or Live have often been out in front as far as the technology is concerned. Pro Tools HD's unique approach of being able to assure studios that the equipment all works together and even if the computer crashes the client's work is still safe counts for a great deal at the sales-face, but you don't half pay for it.
Which is where Craig's point about songwriters amd music creators comes in. The musician/writer/engineer/producer who either doesn't need big studio facilities or can't afford them has been the growth sector in recording for over 20 years now.
