Hello Guys, I am planning to buy a mac book pro, but i couldn't decide weather this is the right time to do so or not. i read many places , where many are saying there is a new version of macs coming soon. I am planning to get a 15 inch one. Does any 1 have any idea of when will the new one come out. The problem for me is my old laptop is lost and i need a new one soon. And will there be a very huge advancement in the 15 inch model ?
