Features which I don't think you could Knock:
- Downloadable Software that also allows you to share on-line (like FlipNote Studio)
- Camera, Sound recorder, Internet Browser and Obviously plays games in your pocket

- Better Sound Quality, slightly bigger screen, camera can be used 'in game', volume control is a button
- You can send pictures Instantly from the DSi to Facebook via Wifi- Most phones require drivers installed and a wire
- Firmware Updates, Nintendo are constantly working on new features and systems to make it better unlike the lite and original which are cut off.
