I've been debating if whether I should get the Penryn MBP 17" MBP or just wait for the Montevina based MBP. What I don't know is, is it worth it to wait? How much better is Montevina compared to the Penryn MBP? I play on using it for College/University so I would be using it a lot, and probably keep it for 2-4 years.
