Thanks for all your suggestions guys.
I just got off the phone with Apple. They were very understanding.
They have already arranged a replacement to be shipped with High priority. I'm told I will have it by the end of this week latest.
They will also arrange for a courier to pick up my old MacBook and said that I could choose when to send the old one back. So I can make sure I'm not without a Mac at any time.
I also asked her what would happen if the replacement Mac had any defects. She said that am entitled to a Perfect mac and if they will replace any defective mac no matter how many times it takes.
Lets just hope the next one is perfect out of the box!
Where do you live? I'm just wondering if them having a courier come pick it up after you receive the replacement is something based on your location. I just received a mba with a defect on the keyboard, and when I called to ask for a replacement, they said I had to send it in first, have them look at it, then get a replacement sent back to me. I really don't want to have to wait another 2 weeks for the replacement, especially 2 weeks without having one at all.
