Nintendo DS Lite Console

I finally broke down and bought the DS Lite. I travel frequently around the world, and wanted something that would add another dimension of activity to the usual dull and long hours of international flights and hours in airports.
What I like about the DS Lite is that it feels like a guilty pleasure - it looks fairly cool, fits in with my business systems, yet I'm just playing games and taking a mental break from the laptop. The start up interface is functional but uninspired, but after that it can immerse you in the simple joy of light multi-screened entertainment.
As a frequent flyer, I can recommend it, just pretend you are working on your PDA and no one will know your escape into Mario-land :)
