I can't believe I'm saying this but after my first personal computer being a Mac and having had one for maybe six years, I'm contemplating leaving it all behind.
I'm on a Mac Mini, and love it to bits, but right now I can see more reasons to convert to the dark side...
First, I refuse to go any further than 10.8 because I'm scared it will slow my Mac down, and hate the look of Yosemite. I don't own any iOS devices and don't want my desktop looking like a tablet thank you very much. The longer I leave it the worse it'll get and I'll have to move forward at some point.
Second, I think price wise I can get more for my money with pc. Unless I pay more for a higher end Mac, I can pick up a cheaper more powerful pc.
Third, I'm not bound by pre-made machines and can customise how I want to match my needs/price bracket. If I need a bit more speed, just pick up a new motherboard and processor and I'm on my way pretty much.
Finally, I do like games. Unfortunately Mac can't quite give the that experience.
I will miss apps like pages, mail and calendar, but I think that the benefits of PC are far stronger.
I am still a firm believer in once you go mac never go back, and you hear very few stories of people moving from Windows to Mac, but I guess I'm doing the opposite somehow...
I don't quite know what I'm expecting by posting this, but as long as we all play nice I look forward to a discussion.
