The 2012 MacBook Pros vs. the 2011 models: what's changed?

Since the epic rise of the MacBook Air, the MacBook Pro has become something of a dark horse in the Apple notebook family. Sure, it may not be Cupertino's thinnest, sexiest product, but it has the heavy-duty internals to handle intense graphics for artists and gamers alike. Apple just announced its updated 13- and 15-inch MacBook Pros -- not to mention a new 15-inch model with a brilliant Retina display, and these new machines boast some pretty impressive upgrades. There's no shortage of spec changes to keep track of, so check out our comparison charts below to see what the new models bring to the table (hint: highlights include USB 3.0, Ivy Bridge and a thinner design for the new Retina model).
