I am in the market for an apple laptop, it will be my first mac! I am going to be using it for the usual web surfing, youtube, e-mail, and music editing. I have read a lot of topics on this, and my debate is wether or not I need the extra screen reality of the 15 inch, or if the 13 inch will suffice? I also read somewhere that the difference between the 13inch and 15 inch screens is like 15 million colors, is that true? Also if you suggest the 13 inch, can it be just a macbook, why or why not? Also are there any MMO's that can be played on a macbook/pro? Are there any books I should pick up for switching to a mac?(Mac's for dummies?) Thanks in advance!
