I'm sure the Nintendo DS Lite has been reviews, scrutinized, prodded and probed to death already, so I decided to take a look at the little things about the DS Lite that you might not know but wanted to find out from someone who had one.
First of all, yes it is smaller than the original DS and is technically better. The screen brightness is better, the size is smaller, and even the stylus is a longer length, even in its smaller form factor. The power button is a slide mechanism on the right side of the DS instead of a button on the left side on the face of the DS. It's much easier to press the power button over the slide, imo. Also, the top of the DS is shiny, and shiny is just asking for scratches, which is picks up in small groups, nothing too glaring, but easily seen from the reflection of light. The matte interior is a much better decision, as it doesn't pickup fingerprints or scratches as easily. The start and select buttons were moved under the ABXY clover and are small 'dots', which can get annoying to press sometimes (and my fingers are by no means meaty). Overall, the DS Lite's redesign is technical and functional, but not necessarily a complete upgrade.
If you get a DS Lite, you know what you're getting with Nintendo's library of games, and what it can and can't do. The little things probably won't affect your decision too much, but I think its something people should just know.
