Because of numerous kernel panics with my less than 3 day old MBP, Apple decided to replace it. I sent it back last Friday; they received it Monday morning. Yesterday(Thursday), I contacted the apple rep with whom I've been working. She explained that she requested my new computer on Monday, but it had yet to ship. Unfortunately, it looks like it didn't ship today either. The letter I received with my FedEx tag said 2-4 days, so I'm wondering what's going on. Also, I have no idea what they're going to send me, a refurb, a new CD, or a new C2D (which might explain the delay?). Anyway, I was wondering about others experiences with replacement computers. How quickly did you receive yours? Was it a refurb/new? Did they send you a tracking number when it shipped? Thanks! Clarification - I was under the impression that the replacement mbp would ship overnight. In fact, the Apple rep wanted me to email her the tracking number as soon as I shipped the computer so that once fedex picked it up she could place the order for the replacement.
