Hello, I am considering getting a mac in a few months or so. I have narrowed it down between the middle macbook or the macbook air (revision 2). I am a student in HS and will probably just do the basics- use it for projects, internet, downloading/watching movies-nothing too heavy such as video editing. I am wondering, since this will be my first mac in awhile, what software/programs I will need for studentish stuff. Thanks!
