Well, today I am the proud owner of a new mid-2012 13" MBP (with a Core i7 ). It's my first Mac, and it's only taken a couple of hours for me to decide that it won't be my last. I have one concern though- how many years can I expect this thing to get updates? It appears that Mountain Lion supports between four to five years of previous models, but now that Apple is switching to yearly OS updates, I feel like we may be in uncharted waters. Could I reasonably expect four years of support for new versions of OS X? I am willing to pay whatever Apple charges for future updates, but at what point do you think they will be less than willing to provide them for my hardware?
