I've wanted an iBook for about two years, and can only now afford one. But, I face a dilemna, should I buy one now, or wait? I have a few concerns. One is longevity of the device. Spending $1,200 on something, I want it to last a few years. Will I be able to upgrade the OS for a while? Listening to some, they hinted at avoiding the first generation of Apple products, because of possible quirks and deformities. I worry that the new iBook (,MacBook, or whatever it'll be called) will have a decreased battery life because of a more powerful processor (one that I do not necessarily need). I'm going to wait until Tuesday to see if they're going to release a new iBook, but if they aren't... I can't see myself waiting beyond that. Any input would be appreciated.
