Right i have had 2 MBAs and BOTH have suffered from slow down when simply watching a avi file. I know it's not normal but my friend said she has the same problem. If i pay £1200 for something i expect to be able to watch an avi file during my lunch break and not have to think of something else to do as it stutters so much. When i got the Air the older MB were in the store and the screen difference between the Air and MB was noticeable. By a fair bit. The air had a brighter screen, i liked the glossy finish too. With the new MB have they improved the screen at all? or is it the same screen? i see apples site says glossy screen, was the old mb screen glossy too?
