First of all, is it Macbook, Ibook or Notebook? I don't know what to call it. My second question is how much of a difference is adding an extra gig of Ram? I plan on buying the $1099.00 Mac with the Student discount. Will my Mac run at a decent speed with how I plan on using it? Here are my uses: Internet Word (Papers) Music DVD's (Long Trips) Thanks for the help!
