I'm planning to purchase a late 2011 Macbook Pro. Although they are missing some features (usb 3.0, Ivy Bridge, etc.) they are a few hundred less than the current 15 inch machines. I noticed that a few online vendors still sell them. I'd like to ask a few questions before my purchase: 1. Do the late 2011 machines have the same warranty as the new (mid 2012) machines? 2. I'm looking for a machine with specific features (large res matte screen, 1 GB graphics card), where can I find a list of the specific model numbers that would specify these features? 3. Other than OS X 10.7 instead of 10.8, are there any software issues that will arise from purchasing a few month old but still new machine?
