I'm the same way - I love staring out the window of an airplane. I'll bring hours of entertainment on a flight, and then spend half the trip just wistfully gazing out the window.
One of my favorite moments (and quite probably a formative moment of my love for window seats on planes) was a landing at Victoria (or maybe it was Vancouver, been a while) airport. I was a young teenager, and was seated just aft of the left wing. I didn't know much about aircraft then, so when we touched down and all of a sudden the rear engine cowling splits in half and rejoins behind the exhaust to form a redirection chute (thrust reversal), and then the pilot throttles up (I've always loved the whistle of turbines and the power of a jet engine) while the plane shudders and rumbles to a stop... I was in heaven. I'm sure my eyes were the size of saucer plates. It was the most amazing thing I'd ever seen, like discovering you were actually riding a transformer the whole time. And that moment of surprise and joy is frozen in time in my memory, along with my love of window seats on airplanes. I'd be sad if they ever took that away.
