Hi all, I am in the market for a new laptop, and I'm very interested in the new MBP 17". The combination of the long battery life and great size / weight ratio are really appealing. I currently carry a 5lb ThinkPad plus a 9 cell extended battery, so the weight would be similar, for a great 17" screen rather than a decent 14.1. However, I am the definition of the 'road warrior'. I'm routinely on at least 6 flights per week, and I'm concerned about the actual size (not weight) of the machine for use on an airplane. My ThinkPad measures 10" deep, and the MPB 17" is 10.6", so not a very large difference on paper, but I'm trying to figure out how it would work in the real world. Has anyone had experience yet trying to use one of these in a coach seat on a US domestic carrier? Is it actually possible to open the screen far enough to be able to see it? Can you type effectively? Can you position it on the tray table so you can use it and still put down a cup of coffee ? Any feedback appreciated. BTW, this forum has been a great resource as I try and gather information for my upcoming purchase.
