I think it's safe to say that most creatives have no clue what runs under the hood.
Apple hasn't been about "What's under the hood" for a good while now, yet they still seem to be quite popular.
For the IT professionals on the other hand, it's a whole different story. But most IT professionals don't care about Apple to begin with. I think a good majority of Apple users use Apple because they are either familiar with it's OS (it's what they have been using for years) or because they just want a shiny system with status. That's the truth. If we were here debating hardware and if hardware was the underlining reason for people jumping apple's gloriously thin and shiny ship, this would have been a discussion put to rest years ago. the "I use a Mac for the Adobe apps, i.e., PhotoShop, etc.," is really just a bunch of horse dung at best since it runs better on my Windows rig than it does on any apple rig to date. Give me one example of something you do on a Mac that couldn't be done on Windows. I'll wait. it comes down to personal preference and status. Although status has been hard to justify lately.
