I would like to get a new mac. I currently have a pc netbook with a 1.5 ghz intel atom dual core processor and 2gb of ram and it makes me want to punch the wall because it's so slow. How different is the i5 dual core from the atom dual core? I want a laptop that will last me a good long time. And money is a small factor but I like the 16 gb option in the new mbp. So it's either the 13"mpa ultimate with i5 and 8gb OR the new retina mbp with 16gb ram. I use it for mainly school, word internet, music, movies, hulu, making ringtones and some light photo editing. I hate waiting for things to load and I hate the spinning hour glass even more. I was thinking of getting a iPad as well for school for note taking but I need full computer functionality. Help I'm new to mac.
