This is slightly off topic, but I really wanted to plug the iPad (and I'm sure the forthcoming Android tablets as well) for use on the plane.
If I don't get lucky enough to score an upgrade, I find it almost impossible to work with a laptop in a coach seat. The iPad has been much better. It fits on the tray perfectly and isn't going to get smashed if someone reclines back. For reviewing digital documents, the book orientation works way better.
Now that Docs2Go has come out with a workable MS-Office compatible suite and GoodReader has come out with a great PDF reader, I feel like I can get some work done at 20,000 feet.
