I'm by no means an "expert", but IMO you will be very happy with the current MBP. A lot of folks on here say that C2D is old technology, but on the Mac platform it works very well, is fast, has good battery life and doesn't overheat the machine to where you can't stand to have it on your lap. I bought one on Sunday and so far I am very pleased with it ( I knew I would be
). Like you, I use the mac for email, web browsing, iTunes, etc. I do not edit video or play games. Users who do all of that on a laptop and complain about speed probably need to be on a desktop machine, just my opinion. There is no way to know when Apple is going to refresh this line, we can only hope and speculate. Besides, if you get into a waiting game, that's what you'll end up doing, waiting for the next best thing. If you have the money and you need the laptop, go ahead and get it now. It is a great machine and you will not be disappointed. Hope this helped and good luck to you!
