I'm using the first revision of the mStand and I bitched about the lack of space for opening the latch in a review. Seems like they got the hint.
That is a pretty sweet setup all around. I like how the setup works with the look of the desk and the scenery out the window. Nice.
To the OP, I use an iLap for home use and love it. Keeps the MBP nice and cool and I like the flexibility and comfort for both chair/bed use and desk use. Angles are good, stand is comfortable and is lightweight yet durable. I'm very happy with it, though admittedly I do not use it for travel.
