I myself grew up using a PC so I guess that is something I will always be used to. I remember when I worked at a school and they used Macs and I was unable to get on with it. I guess it really depends on what you are used to.
I used, I'm using and I'm going to use Windows or Linux OS forever. I don't even dare to touch an Apple product. They're too expensive in the initial prices to buy them, in the support prices, in the spare parts prices and also in the OS upgrading prices that come every 6 months as I heard. I'm already happy with PCs and Laptops.
I don't own a Mac, they are expensive to purchase. I do prefer a PC because it is more easier to navigate and use. I suppose this is because I have got used to using a PC with windows operating systems. For my overall decision on this, it would have to be PC all the way.
