I'm thinking about buying a refurbished iBook from the Apple site. It costs $100 less than the education price on a new one, plus I have a $30 coupon. Two questions: 1. Has anyone ever bought a refurbished model? Are they really as good as new? 2. Does the Apple Online Store charge sales tax? I tried to go as far as I could in the checkout to find out, but when it got to the part where it wanted my credit card, I decided it might be better to ask here. I figure if I can save $130 PLUS sales tax (I had planned to buy at my local Apple store), then I won't feel too terribly bad if the iBooks get updated in the next couple months.... Thanks, folks!
