A laptop in every (airline) seat
Now this is cool! Singapore Airlines is putting a Linux laptop in every seat. I had the opportunity to use my laptop with wireless on Luftansa flights via Boeing's Connexion service referenced here and that *really* made my life useful. Now if they combined this with a Xen base for that Red Hat version, you could install your own OS and images on a USB key or a USB disk, boot your own environment, and be up and on your way.
Now where does Singapore Airlines fly? I have to figure out my next boondoggle! ;)
