I'm going to buy a Penryn MBP next week from the Apple Store in San Francisco and I have a few questions in regards to what I can expect. I've always bought my Macs online or through Craigslist, so buying a new Mac in person is a whole new world. First off, what has the availability of the Penryn Macs been like for the Brick and Mortar stores? And do they just sell the base model, or are they able to BTO in the store? I'd call the store, but I answer phones all day and the second I think about calling the store, the phone (hold on a moment, phone), rings.
