I want the macbook for music, movies, photos, internet, school work etc. I also use photoshop but only for light editing and 1-2 a week. To give you an idea of how much memory i would need, i currently have (30GB, movies)(8GB, music)(10GB, photos) I'm leaning towards the 13" 2.53GHz because i love the smaller, more portable device. I also plan on purchasing a LED cinema display so i don't mind how small the macbook is as i'd have the display to compensate. I plan on using this setup to replace my current PC so it will be my only computer. Are the specs for the 2.53GHz enough for my needs and to be used as a main computer? Does anyone recommend one of the 15" models instead?
