I am converting from desktop to notebook computer, and have decided, after much thought, to not only buy my first notebook but my first Mac. I'm pretty set on the 15" PowerBook, but the $1800 sticker (after my student discount, that is) breaks my heart a little bit, so I'm considering saving $400 and buying refurbished. This will also be my first refurbished computer, so, as I'm sure you can imagine, I'm at a bit of a loss... Does anyone have any experience with and/or advice regarding apple certified refurbished computers in general OR the refurbished PowerBook specifically? What are the specific problems/differences I might run into with refurbished versus new? I'd be willing to suck it up and just spend the 2 grand on a new one if it makes that much a difference since after all, it is an investment, but I'm a little reluctant (though tempted) to get the new MacBook, as I have trouble trusting anything first generation. If I do end up buying the refurbished, should I go with the longer warranty? I've heard from several sources that whatever defects are going to pop up and give you trouble will likely pop up within the first year anyway, but seeing as it's refurbished, would I be better off with three years of protection instead of just the one? Thank you so much for any and all advice... I'm slightly lost.
