I'm looking to buy a new MBP after the new update as many others are also. Obviously when spending so much money on a powerful laptop, we expect it to last 3-4 years. The computer world develops so quickly that it seems like things are quickly getting outdated. If we were to buy a MBP after the update, what can we expect from Apple in the next 4 or 5 years? And how does that compare to the longevity of life for the MBP? Obviously the specs for the current MBP aren't going to be as good as the one 4 or 5 years from now but how will it compare? Will it be worth the money?
