A side by side comparison of the Nintendo DS Lite (left) and the Nintendo DSi (right).

The DSi has a new skin: a matte-black (almost dark gray) color that feels much rougher than the DS Lite. The roughness allows for better grip of the system, as well as improved scratch resistance.

The DSi is 3 mm thinner than the DS Lite, while its length and width increase by 4 mm and 1 mm, respectively.

The DSi comes with 3.25" LCD panels, a full 0.25" larger than the previous model's 3" panels.
