People use Apples because they started out with them and PCs feel awkward. Many Apple users have learning-curve issues. But artists generally prefer Apples, even when their art businesses make them use PCs.
At least half of all Mac users are ex-Windows users who have made an informed choice of the better platform.
The fact is that almost ALL Mac users are also users of Windows... and as a result are better informed of the relative merits of each platform than are Windows users, who in the most part, have never touched a Mac.
I recently switched to a Mac for many reasons:
1. The Mac Pro is easily the best put together and thought out box on the market.
2. I have less worries in regards to spyware and viruses.
3. All the programs work together seamlessly.
4. I can run VMWare Fusion and run Windows (XP or Vista) in a window and have access to the few programs Windows does better, like financial software.
I am a musician, photographer, writer, programmer, web designer, and financial adviser. No one operating system met my needs, but a Mac running Fusion can meet EVERYONE's needs!
