As I have said before, Apple has been in trouble ever since the passing of Steve Jobs. Now, with the latest rumours of this Macbook Air and the potential setback due to component issues, I can only guess this is going to be a non-starter. With tablet devices and Chromebooks being a hit, Apple shouldn't be focusing on 12 inch laptops that simply have a supposedly 'lightweight" frame. A keyboard attached to a screen for the price these guys are sure to be charging is a sure miss!
