Hi guys, I'm new to the forum and a potential switcher. I have a question for those who have been in the Mac world for a while. If I buy a Macbook Pro within the next few months, how long do you think it will be before I need to upgrade again? That is, when the software is so much more advanced, or there are incompatibilities with my Macbook, etc. Or when the hardware just doesn't keep up with the tasks that I want to do. I'm trying to justify the extra cost of getting a Mac with the fact that it might have more staying power than a cheaper PC. Let me know your thoughts.
