OK. So I read the two threads below me about G5 updating, and my question is similar. I just didn't want to hijack their threads. Send me back there if my question is answered. I'm planning on selling the two machines listed in my signatures, and will probably upgrade with a macbook and a mac mini. The question I have is about the macbooks. I don't really know too much about them. How "out of date" are 2007 models in terms of functionality etc.? (don't say two years...lol) I'm not really familiar with the differences in speed and stuff on the Intel macs. I just figure it's time to get out of the PowerPC world. Thanks in advance.
