Hello, so I ordered a Macbook Pro, the lower end 15" to be precise with a higher res display (other than that: stock). So I was wondering... It says it will ship within 3 days and be with me in 7 days or after that... So far so good. Does this mean that Apple will build it for me and ship it to me from China or do they keep certain configurations in stock so they can ship "custom" orders quicker?
