My local gamecrazy was doing a deal where if you traded in your DS lite, you'd get 80 bucks off of a new dsi...so I decided seeing as I was gonna eventually upgrade down the road...might as well take advantage of the deal.

anyway the screens are alot clearer and noticeably bigger. Not to mentions that the buttons are nice and clicky. It should make hitting the diagonals alot easier compared to the lite's squishy d-pad.

I also downloaded the web browser app. It's alright for browsing forums nd stuff...but I can't view youtube videos on it :(

All in all I think it's a solid upgrade if you get past the fact that there's no GBA slot (not that I even play GBA games anymore)
