well. I am a hard core PC fan, so i would tell you everything thats wrong with a mac but since your not a gamer, thats a different story.
PC pros> Can run Games, supports a hell of a lot of hardware, can be upgrade if needed and software and controls 90% of the market. (if i am wrong, please correct me)
PC cons> Can get a virus, can be hacked, can over heat and/or catch fire.
Mac Pros> Greet at movie making, very easy to use if you only going on the web and checking e-mail and other websites like myspace. and theres almost now virus and haclers don't bother mac users
Mac Cons> Can crash randomly sometimes, If ya delete a important system file, your screwed. Not alot of programs work on it and your can't upgrade most macs if the need comes up.
this is from past incidents that have happen to me or friends of mine. I am still a PC fan and i don't think i will be getting a mac soon, even tho i think it be cool to have both a PC and a Mac
