I bought the cheapest MacBook Pro (13", 2.26Ghz, 2GB RAM, 160GB HDD) for now but in the future I think I may need better specs, especially if I ever want to set up Boot Camp. So I have a few questions before I seriously consider anything. What are the max tech specs I can put into my machine? Is it possible to even upgrade the processor? What kind of screwdrivers will I need?
