Hi, I'm a new switcher and have not purchased a Mac yet but will buy a 15" Superdrive before summer ends before I'm off to college. Does anyone know the approximate average length of time it takes until a new product becomes listed on the Apple refurbished site? I have been looking at using ADC but was called from Apple yesterday and told that I must be taking classes to enroll and that would mean I can not sign up until I am already in school which would be too late to purchase a powerbook since I will need it before summer ends to learn the OS. So I changed my mind and decided to go for refurbished since it is still much cheaper than the ADC discount would be. Does anyone else recommend this? If powerbook updates do happen this month or next, do you think those changes would make it to the refurbished site before September? My guess is no, but who am I to say? A refurbished product would be just as good right, seems how I can get the same Applecare. Are they returnable if they have a few scratches? Thank you so much.
