    For the past few weeks I've had a refurb 13in/1.86Mhz/128gb/4gb Macbook Air. It is great. (I probably should blame/praise Scottsdale for finally tipping me over into the purchase! :) ) I won't go into all the good things about it because more computer-savvy folks than I have already spelled all that out...

    I "dock" the Air with a 24-inch Apple Cinema Display, and it all seems to work together wonderfully. No complaints there. I did notice, however, that when I was trying to view a full-screen HD program that I had downloaded through iTunes, the playback stuttered a lot. The problem went away when I made the picture smaller than full-screen (although it was still plenty large.) There's also no stuttering if I just watch the program on the MBA itself.

    Is this just a built-in limitation of the Air? If so, that's fine; it's not a dealbreaker for me since I don't plan to use it primarily for that purpose. But I also wanted to make sure this wasn't a sign of some kind of problem.

    Are you running your MBA in clamshell mode while it's connected to your cinema display? If not, I'd suggest you do that as it allows the Graphics Chip in the MBA to direct all of its power to the monitor instead of splitting the power between the screen on the MBA and the screen on your monitor. This is most likely what's causing the stuttering.

    If you do not know how to put the MBA in clamshell mode, refer to the link below.

    I hope I was able to help. ;)

    Please reply back with your results.

    Hi! I was using my MBA in clamshell mode when I was having the problem, but I decided to try it again, and now it seems to be fine. Huh. I wonder what the earlier problem was. Perhaps there was some kind of background process going on that I was unaware of.

    Well, at least the problem is gone. ;)
