I am very intrigued by absolutely fantastic specs current Macbook Pros have. Maybe even thinking about ditching my Macbook Air + W510 for a new macbook pro 15". However a have a few questions about the whole thing? 1. Can the optical drive in Macbook Pro be replaced with a 2nd hard drive or solid state drive? Can that drive be made to be bootable? Is it a major surgery to get it in there? 2. Can 2 monitors be hooked up to MBP while running them in extended desktop mode (not duplicating)? 3. Did Apple use revised version of chipset or is the SATA bug still present?
