Ok, I am really tiring of my 4200rpm drive. Problem is, it is not a user replaceable part. I have applecare, and I am not waiting three years to replace it. can i take my book to an apple authorized reseller, and my new FAST hd and have them swap the two, and still be under warranty? i might just do it myself, and if i have problems just put the old drive back in, if the tech wants to change me too much. 10 minutes of work is NOT worth $60.
