Hi I currently have an Advent laptop which is shockingly crap. No space for a desktop pc. I want to buy a macbook and make the change from windows to apple however I have a few questions which id like some non biased opinions on plz. Firstly does a macbook open Pdf and word documents? Or do I have to buy a special programme to do it? Also what about powerpoint if I need to do a presentation? Or windows movie maker for makong films? And does it work on websites that require adobe flash? As I know the ipods and ipads dont.I also heard you domt need any spyware programmes or antivirus as apple has its own is this correct? Thank you
