Best system and best print by Miles. And it's $20 less :P
The DSi is quite sad really. Goodbye GBA slot and fun functionality. Worse battery life not to mention the OS part of it being really bad. The icing of the cake is how the DS Lite is even better at music playback due to the Nintendo GBA player supporting more formats than the DSi.
