2.4Ghz white macbook for about a week. Enjoy everything but do not like the screen. Want the LED screen on the air or the mbp Would rather have the multi touch pad, instead of this basic macbook pad. Mainly the screen is what I would like the most, just dont know which to exchange into because I do basic things on the mac just surf the web, photos, music downloads etc etc. Pretty soon getting into photography so will be running photoshop or something. Will MBA hold those basic things plus that, or better for the mbp?
