Okay I'm back from the DSi event. Pretty much there was about 10 people partitioned off to the side of the Gamestop and we all stood around playing with the DSi. I forgot my games so the only game I tried out was GTA and the touch screen feels cramped on the DS screen, but not on the DSi. It also has a better grip because of the matte it doesn't feel like the plastic DS shell. The speakers are very good we well, but still not great because of the sound in the store. The cameras are pretty nice, nicer than what I thought it would be. The controls are very intuitive, anyone can pick it up and get it going. I put an sd card into the game- funny I thought the slot cover was an actual hinged door, but it's actually a latch that you pull out. The system recognized my card immediately, but I access it was difficult and I couldn't figure out how to save to the card. The DSi is longer and slimmer than the DS, the buttons felt stiffer too. Overall it was a nice low key event, the DSi is pretty much what everyone's expecting. Oh and the online features were disabled so I couldn't try any of that out.
I was asked over the phone to not take pictures, but I got one pic of me holding the DSi

They gave me a card that will save me 100 bucks on the DSi if I trade in my old DS, but I preordered it at a different store. They printed out a pic of me that I took with the DSi and gave me a magnet frame with tinier magnets of DSi icons- finally I also got a DSi key holder the kind that goes around your neck.
Not bad for a Sunday!
