I bought a black 2.4 macbook 1.5-2 month before the new alumin macbooks came out. I didn't know that they were about to come out. I mean will Apple from now on always develope and release new laptops every 6-7 months? Is the the black mb 2.4 really obselete compared to the alumin one? Because i've read a lot of people writting that games and etc that work on the alumin one would've never worked on the plastic one. Thank you for your answers in advance.
