I'm going to sell my Nook Color, and am looking at getting an iPad. It seems like the only difference between the iPad 2 and the new one is the screen. Has anyone seen the new one? How much of a difference does the retina make? I could save $100 if I went with the second iPad. I want to use the iPad for when I start college next year, and it's just more useful then a Nook. I will be getting a new macbook pro as my main device though.
