I was in a store today checking again the ibook12”. I also play a little with the powerbook and I start thinking about it . The powerbook will give me a larger disk drive and a dvd-r. I am willing to pay a little extra if I am gonna to enjoy it more and having it for more time. I want to know a little more about about ibook12” in comparison with the powerbook12”. Battery life? Performance? Durability?
