Very Slick. I downloaded Word Waster it's a cool cheap game I liked. Only problem is it just supports bold and storm at this time.

They need to make this type of device with out the need for the USB connection. Maybe toss in a cheap modem that dials up to a carrier every 5 minutes and checks for messages... What's the use if you need a computer on and nearby..

This is certainly a space that is heating up, Nintendo and Disney just annouced a trial to use the DS to guide kids around(search DS disney on engadge), but I can't imagine that's too open a platform. There is also a company called Flick Software who has a product, the mobile interactive guide, http://www.mobileinteractiveguide.com that seems to be a very open system for content providers and venues. They also seem to be device independant which seems like an obvious feature seeing as hardware changes and improves every 6 months..
