Nintendo 3DS sampling schedule
 

Up until the end of this month, there will be places where people can go to sample the 3DS. Mind you, they're only in four cities; Los Angeles, San Francisco, Chicago, and New York. This link has the dates, the times, and the locations.

I got to try the 3DS today at a Best Buy, and played Pilotwings Resort. I never thought I'd say this, but the 3D feature is actually somewhat gimmicky. I don't think I'll be using that feature a whole lot when I get a unit. I won't be getting it at launch either, but after I've tried it, I think it can wait. I'll wait to get it until a game that interests me comes out for it, whether it be a 3DS game or even something from the Ninendo eShop.
