boy did you open up a can of worms! PC vs Mac almost as good as Tiffin vs Winnebago but really i am not sure anyone answered your question. LOL for that matter neither will I but here goes "nothing".
Both will do what you want them to do. And if you are like me after you buy one you will think "Why didn't I buy the other". Personally I use both and they both do about the same stuff. Sometimes, when I am writing a new book, I find the programs i use to format that book work better on Mac but PC can handle it just as well. Mostly that is because the software came out for one before it came out for the other. It really comes down to what you want to spend. and yes to those arguing about apple products vs Microsoft I have an android phone my wife has an iPhone. I use an iPad she uses the Nexus 7. I use a MacAir and a HP pc....it goes on and on and on...they all work!
