I was always a PC user, and having had some experience on MACs many years ago (90's and early 2000's) via work and friends was disappointing at best. I currently use a custom built audio PC as my studio, and it is a single purpose machine, I don't do anything but run Sonar and the rest of my studio. It has run pretty well for the past few years. I have had a problem with the custom PC during this time requiring a new motherboard, that began with a corruption in Windows that to this day I have no idea why. I have on very rare occasions even had some alleged disk corruption or errors that required scanning the hard drive. Even a blue screen once or twice, though not a deadly one.
That same year (2012)that I purchased my custom built machine (about 2,100 bucks I think) (I'm thinking for my next maching,Mr. Roseberry, I'm going with you, just so you know, sir) I looked at a Mac mini for a friend, and decided to replace my aging PC laptop (non studio) to use as my everyday machine, and got the Mac Mini. This Mac is definitely the best computer I have ever owned, and while I don't do anything strenuous with it, or do any of my music on it, I easily upgraded the RAM to it's max (16), which I bought from 3rd party, popped it in within 5 minutes or less) and now I just keep it up to date with the latest OS X versions, etc. This machine has not only been virtually flawless, but it still runs a beautifully as it did when I purchased it.
I don't know for sure if the hardware itself is superior to a high-end PC, but the user experience is fantastic. Once you consider the integration with my iphone and ipad, the system is convenient, fast, and virtually trouble-free. I don't know if using Logic would give me the same experience (with a more powerful Mac, of course), but I believe that most folks' love for Macs are not the result of marketing style over substance. I believe their whole ecosystem is superior, and if it weren't for my love (and familiarity) of Sonar and my I would at least consider switching to a MAC for my studio, too. I'd love it if Sonar was written natively for Macs, as well.
The new mac Pro has obvious drawbacks, though, and I am not sure I'd consider using an iMac (even a loaded one) as my studio computer.
So for my Sonar studio I use a PC. For everything else. My little Mac Mini is a joy to behold.
Nuff, said...I'm out.
