dam, no. All i have is a puny ipad right now. Id demand they send u a replacement, and make them send it to u before you return yours so u dont have to wait another 3 weeks to use a computer.
I would take it back or send it in. My rMBP is supposed to come in a week or two and if I see ANY issues I will be calling Apple. Since the nearest Apple store is about 3 hours away (and I wouldn't get a new laptop fixed anyway) I would talk them into letting me keep it until the replacement arrives...
