Hello all... first time posting! Looking to be a mac, currently typing on a 2005 Acer Aspire....... SO. I dont want to buy my mac right now and then have a redesign come out that blows it away. I have heard that there will probably be ultra thin 15 and 17 laptops... Wondering what the thoughts are. Will they merge the Air/Pro lines? 11, 13, 15, 17 macbook Or will they have side by side lines? 13, 15, 17 Pro 11, 13, 15, 17 Air Or something else? Anyway, I thought I needed some input. What do you expect for the next refresh in terms of hardware.... Thanks!
