hello, I've saved up money and ready to buy me my very first Mac book (pro/air/r/c) lap top computer, however I can't pull the trigger yet. I'm very confused to what to buy and when to buy. im needing one for a personal home computing purpose. I will mostly be using it for e mailing, web browsing, Skype chat, downloading personal photos and editing and organizing, then also use itune alot by importing music from cds, itune/amazon digital purchase and then ripping ( burning?) them onto empty cds or into my ipod. I also like to watch my dvds in bed or on the plane if I travel, especially foreign reginal coded dvds. Do I need Pro or Air ? Do I need Pro or Retina ? Do I want 13" or 15" ? Do I buy new or used with many memory up grades like 1TB and software such as CS5, etc? Do I buy refurbished from Apple web site ? Do I need an Apple care ? I've used and owned Mac since the 80s and never looked back. all my desk top (my current is power Mac g4 dual mirror drive lol) had never given me any issues. What about wireless device.... Do I need Airport Express, Time Capsule, or Extreme? new model with "ac" or older model with "n" since none of ? the Mac book currently support "ac" yet? Finally, do I wait few more months ? until new model comes out? I know I have so many options and it's a very big shopping for me. I worked very hard trying to saving money for this. I'm looking to do the best purchase for the money and I'd like your advice/opinion/help please.
