I've got an opportunity to buy a MacBook Pro 15" with 2.3 processor, 8 gig of memory, 750 gig drive, high res glossy screen for $2400 shipped. Laptop sealed in the box ready to go. My questions is, do I buy this now since it's a great deal, or do I wait for Lion to come on out on the MB Pros? Any advantage to waiting or just get this one now and upgrade to Lion when it's released later this month? Thanks guys!
