Maybe you are right and PCs will never gain a foothold in the image processing industry. My point here is that earlier quotes of 7% of the computer market is even smaller considering Apple no longer has technological corner on film editing. I do not work in the creative industry, although I was a member of my college film club abd had several film student friends who used Macs and their digital film editing software. Currently I am hearing that PCs and the PC version of the software is killing them on prices, making it much more appealing. Perhaps it would be more appropriate to say something like:
"independent film makers, small busisnesses, students, people new to the industry, and people who are not already heavily invested in Apple and their software are finding that the premium for Apple is only for their sleek logo, and less and less for their performance etc."
I agree that Apple is tailor made for image processing and film editing, however I think you can do it just as well on a PC, now that they have caught up, and do it for a little bit less money. However, just like anything, that doesnt apply to each consumer, especially not those who are already invested with Apple or those power uses who can afford to pay significantly more money for a small increase in performance because their jobs require it.
I have always used PCs at home and for work, and have never had major issues that so many people blast them for. The biggest problem I had was with a virus, and in the end a simple re-install allowed me to both save my critical files and completely re-install windows and get rid of the problem. If my custom build PC at home burst into flames and melted into a lump of aluminum, I could buy all new, better components and build an entire system for the same price as the first one, and still come out ahead of one expensive Mac. I know this does nothing for the lost time, files and work, but there are backup systems for these kind of things that I am sure you would use regardless if you are on a PC or a Mac. I think that the reliability of PC vs. Mac is becoming more and more like the reliability of Ford vs. Toyota (not alluding to the recalls). The reputation of Toyota is why people are buying Toyotas, despite the fact the Ford's reliability and quality is probably equal to Toyota now.
