Hello everyone, I'm pretty new to the Apple World. So here I go.. First of all, English isn't my mother language and this might also be the root of my problem. As I was wandering in the Buyer's Guide, I have noticed that there are different words for explainig what Apple has in mind for its products. For example we can talk about a whole "update" of a product line, if there are major internal improvements and also a whole new design to the line, such as the alu-unibody of the MBPs. And there are the words "revision", "review" etc. So my question is this. Is there really a difference between these words? Are they really used for spesific improvements in periodic times? If so, could you please explain me what they mean? Or maybe not even slightly important are these words? I would be very glad for every answer. Thanks a lot already!
