I bought two Nintendo DS's and World Champsionship Poker DS edition.  World Champsionship Poker DS allows you to send the game to other DS players even though they do not have a copy of the game.

The wireless range in an office environment is amazingly 30feet through two walls!

I enjoy the ability to hold Shining Soul II in the GBA slot and a DS game at the same time.

The sound on the DS internal speakers is much better than the Gameboy Advance.  I play Shining Soul II on the DS for this reason.  Using high quality aftermarket headphones yield an even better audio sensation.  You do not need a special adapter for headphones on the DS.

The DS will charge off of the Gameboy Advance's battery charger.

You can expect at least 3 hours of battery life from a Gameboy Advance Game.

I do not like the stylus.  However, drawing graphics in Pico chat is fun.. somewhat.  Pico chat should have more options for notifications.  Such as notification when another DS is detected in the wireless area, but not in a chat room.
