The SHOCK! case is essentially a complete overhaul of the Nintendo DS Lite housing. It comes in a variety of colors, including clear (although I guess clear isn’t technically a color, but yea you get the point), so, like Raj, you can color coordinate to your hear’s content.
More importantly though, the SHOCK! case provides an update to the brittle hinge found on the DS Lite. There is also an update to the speaker that allows the driver to produce fuller sound. No word yet on pricing or availability, but we’ll keep you posted as that information becomes available.
