I'm going to be updating soon, and I'm curious how much of a difference the current MBP will be performance wise compared to my 2006 Black Mac? I have the 2 Core Duo now, 2 GHz processor, with 4GB of RAM. I'm running OS X Lion 10.7.3 now without any problems to speak of. Am I going to notice any real difference in performance? My current machine isn't bad, but the case is getting cracked and the battery is starting to crap out. Are there any graphical differences? Will response be superior even with the slower chip? Should I get 2.4GHz dual-core Intel Core i5, or.. the 2.8GHz dual-core Intel Core i7 ? I plan on sticking with the 13 inch version. Would it make more sense to wait for the Spring upgrade with Ivy Bridge? Will an anti-glare screen be available then? I'm mainly using it for documents, (document creation with Pages, and stored document management), online news gathering, and some light photography with Aperture. It's also the hub for my iPhone 4S and iPods. I have no use or need for Winduhz, and don't use it for games. Thanks for any input!
