DSLite is way too small. I'm not a big guy, but I have "piano player fingers." I tried playing my son's Lite when my DS' batteries died and damn did I get a cramp! From only an hour of playing!! >_>
If I had $150 to blow I'd buy a Lite, take the bitch apart, and put all 'teh good stuff inside the normal version.
But still, congrats on your purchase. ^^ Buy some Pokemon.
