It's a new experience for me. Normally when Apple introduces a new product generation I am kind of sad if I cannot afford to upgrade. This time everything is different. I love to work with my April'08 Penryn MBP. It's rocking stable, very high performing, quiet, and even has a matté screen, which I prefer. It's built entirely on Intel parts, having an excellent reputation for the quality of its (comparably expensive) chipsets. I'm very happy to be able to work on that platform which hasn't crashed once since its purchase. Nvidia has some way to go to reach the same reputation for its chipsets. I used to own a Desktop board, when they were the first to supply dual-channel RAM controllers. With regret I remember all the times reading readme-files of various drivers over and over again listing incompatibility issues in combination with Nvidia chipsets. I never got the board to run as stable as I would have liked. It finally died after 4 years. I'm totally satisfied with my previous generation MBP and wouldn't even upgrade if there was an inexpensive replacement program? Who else?
