I have been using a 27" Thunderbolt display with my Macbook Pro for the past six months, and I absolutely love it. For all of this time, I have been using two screens: the display and the Macbook screen. I have been using an external laptop stand, external keyboard, and external trackpad. Using clock coordinates, the display has been located at 10:00 on my desk, and the fully expanded Macbook is located at 2:00. This works OK, but I sometimes feel that I'm missing out on the true advantages of the larger display. Because the screens are angled toward one another, I typically only focus on the right side of the widescreen display. As an experiment, I put my laptop in clamshell mode and repositioned the display so it is directly in front of me. This *seems* to be an improvement, but I'm not sure if there is a better way to organize things. I realize that this is entirely subjective. Nevertheless, I would love to know if other users have a similar experience. If you have a Macbook and an external monitor, do you run the Macbook in clamshell mode? Thanks!
