I am looking to buy a blackbook soon, but I'm not sure if this is a good time to buy. I do need it, but I can make do on my iBook g4 for a while longer. Any ideas? I would like to get iLife '07, but it's not absolutely necessary. Also, my wife has a 17" g4 iMac that is getting a little past it's prime. I was thinking about getting her a 20" iMac because she is making DVD's of our daughter all the time. Her iMac is not quite up to the task, anymore. She has said she would just like a newer laptop than the iBook instead of the old iBook and new iMac. But, for video storage and encoding, I don't think that buying her a macbook and no new iMac would be the ideal setup. With the new iMac, I can attach a external HD pretty easy and have plenty of storage. Any ideas?
