Seems like the camera(s) and free browser are a nice addition... especially now that it can play AAC files natively. If the online store selection gets better than maybe it will be worth upgrading. Still, though, it really doesn't seem to be designed for people who already own a DS Lite... No way I'm going to pay $170 for a small amount of new features.
This is most definitely exciting. The end of retail gaming seems to be a ridiculous jump, but if it works as well as they say I know I won't be upgrading my PC anytime soon...
