Hi everyone, I was hoping to get some input and advice on my near future Apple laptop purchase. I have been using a MacBook Core Duo as my solo computer but it is starting to show its age. With the new Santa Rosa Core2's and a 15" LED vs 13" screen I feel like this would be a significant upgrade. My only hesitation in seling this MB and buying a new 15" MBP is whether or not another upgrade will happen around the time Leopard comes out. I don't mind buying a copy of Leopard and upgrading later on. Do you think that there will be a significant upgrade to the MBP by the time Leopard comes out or is this as good as it gets for a while?
