Ok so my 17" powerbook is done for and I was already looking at getting a new MBP. The question is now the right time to buy? I know according to the buyers guide it is in a neutral point in it's life, but is there anything that I should be expecting in the next lineup? The only thing I am really curious about is usb 3.0 but with apple's record of waiting so long to adopt something this new I would think it will not show up for a few more models. What is everyone else's thoughts on the matter?
