I use both a Mac and a PC. I run Windows for a handful of tasks, like writing and my tablet software. I got a Macbook Pro for my use at college. SInce my major involves both hardware and networking, I wanted to tackle Apple to get a complete view of the computer landscape. It was also an excuse to start using Final Cut Pro.
    When it comes to Macs and PCs, there seems to be a few schools of thought. Macs are overly-simplified. When it comes to troubleshooting, the options are very limited, whereas with Windows machines, the amount of knowledge of hardware is increased. More people use PCs running windows, so there are much more developers who have intimate knowledge of the file structure. Apple is notoriously protective of their OS, and their licensing agreements. Their first party software is the core of all that they do. Windows third-party software is nearly infinitesimal. Government use, and public organizations have implemented Windows in a myriad of equipment and processes, further refining technical tweaks.
    Final Cut Pro, and Soundtrack Pro are definitely impressive, but even they have their flaws. I find the PCs have a better time shrinking video files without noticeable quality loss. Also, my Sony Vegas programs have the option to "plugin" or integrate codecs from other applications, like Divx, making it part of Sony's render engine.
    PCs are cheaper, but these days the gap between windows and Apples hardware is closing. But, I have assembled both mac and PCs from all core components, and I have learned a few things about Apples programming abilities. Namely, the folks at Apple really know how to utilize the computers resources much more efficiently. the way I like to phrase it, to compare an Apple machine to what would be a comparable PC, just take the Apple's computer specs, and double it. Windows 7 is a resource hog, especially in Aero mode. I ran a Power Mac G4 for years, and it ran the Final Cut Pro Studio 2, to my satisfaction. It couldn't handle the larger resource-based program, Motion, but everything else ran in real time well enough. The biggest drawback for me was the vast amount of time needed to render in FCP, but that was only because my paltry G4 met the low end requirements for installation. But, this should show you the potential longevity for Mac hardware. Computer years are like dog years. That 10 year old G4 was like an elderly senior citizen amongst livelier, newer systems.
    However, the inevitable truth remains: the vast majority of people use Windows. The creative industry is heavily embedded into using Apple, and it's pretty obvious why. Creative people tend to use a different part of their brain that logical, math-oriented individuals. In other words, a lot of creative people aren't mechanically inclined, and can't tinker with a computers hardware or programs very much. Hence the begginer-friendly approach to their system.
    On the other end of the spectrum, using Windows can be dangerous. Far and away, most virus are programmed, and aimed, towards PCs. when it comes to inflicting the most damage with malicious programs, hackers tend to think big. And there is no bigger market than PC users. In the days of online intrusions, and identity theft, this is why I intend to use mainly my Mac online. My other PCs are strictly for render farms, and specialized software.
    Whichever format one decides to follow, I think people should embrace technology. Although some of my writing has an old-fashioned tone, I think that artists can greatly benefit from the advent of digital work. Things like tablets, stylus, and just Photoshop by itself is a thing of wonder. I enjoy having the option of undo. Whenever I'm working hard on a project, and I mess up, it's a piece of mind to be able to step backwards, and omit mistakes. You can't erase a brushstroke in real life. Not to mention, there's no cleanup of dust or paint chips. I'm messy enough as it is, LOL. The software has gotten so advanced that its like a digital rennasance. 3 words: God of War. 'nuff said.
