I leave tomorrow for a business trip. Here in Colorado, they don't sell MBP's in the stores with the 3 GHz processor or the 256gig SSD. Once I get to Boston, can I go to the Apple Store, purchase a new MBP, and, with waiting, get both the memory and processor upgraded? I'd like to leave my current computer home with my wife, as her laptop crashed. Via phone or internet, they say it would ship in 1-3 days and, for a fee, shipping takes 2-3 days. Sorry, but that's too long. Sorry for the noob question. I did search both this site and the Apple site and was not able to find an answer. To those who can and do help, in advance, thank you.
