I currently have the old macbook pro 2.2 ghz (15"), 4gb, ram, but its been running slow, battery life is only 33% (587 recharges) and my charger is pretty busted it has problems charging, i have dings, scratches, bumps, cracks, and dents everywhere on the computer. I am looking to buy probably the 2.8 ghz macbook pro or the 3.06, and im not sure whether to get the 15" or 17" 1st: should i wait until the upcoming media event because they could add blu-ray or something? 2nd: Would it be smarter for me to wait a while until they update them? 3rd: Is it worth it to get the 3.06 over the 2.8? 4th: Should i get the 15" or the 17"? Thanks!
