The 17" are really cool. But not practical for a laptop. If you will use it a lot at home, then maybe it is worth it, but to use that sucker somewhere on the road, like a car or a plane, would be pretty hard. 15" is a decent size screen for a laptop. I have a 15" that I brought on a trip to Florida on a plane, and I could BARELY open the it enough to watch a movie. I was right on top of it.
