If you're a dedicated DS gamer, chances are you've spent quite a bit of time with the handheld, well, in your hands. After all those hours of play, we're willing to guess that there are things you like about the design (whichever one you have) and things you don't. Now, we're not looking for a Lite v. Phat debate here -- we've done that -- but instead, we hoped to discuss the position of the buttons, the D-pad, the weight of each version, the size ... all the things that make up the hardware we know and love. Which aspects are great? Which would you change?
