So, I'm getting ready to buy my first Mac. Got my sights set on a refurb'd 15" Macbook Pro, but I had some Qs first: If I were to purchase a new Merom MBP, where would be the best place to do this? Obviously for a refurb I'll go to the Apple Store, but I'm still debating refurb vs new. How often is the refurb stock at Apple updated? Bags: I hear that both Crumpler and Timbuk2 make great messenger bags that fit Macs well; what specific models do you all recommend, and equally important, where to buy from? Although I like the MB form-factor better, I'm going with the MBP for the dedicated graphics. Any other general advice you all can offer?
