I just ordered my third mac, a current iBook 1.33Ghz 12".
If people haven't noticed, in the Apple refurbished area they are offering the iBooks at 21% off to remove the stock they have. Usually it's only 15% off. Also, this isn't a previous generation iBook, but a currently stocked and sold one; the only disadvantage is you don't get the new iBook case
Anyway, after talking to the Apple rep it's first come first served. $800 for an iBook is a great price stating most people who are looking at the iBook line don't need a MacBook. You can only type mistakes so fast. Also, for the $300 more than a used iBook G3 it is definately worth it!
Just letting people know
