Awww yeah. Awesome review, Cheapy.
I also got this one back in December when it was on sale, and I've actually really enjoyed using mine. I've used it more than I originally thought I would, mainly to have the touch screen held up at a good angle. That comes in handy while playing text-oriented or other simple-stylus-control games while eating dinner, or while just sitting back and enjoy dual-screen videos, or to have both screens visible while using the computer (say, while waiting for other players in a WiFi match) -- and it's all come in handy. It works well, too, for keeping the system centered between two people, if you're playing a chapter of Phoenix Wright together.
Another cool thing? It actually works great when lying down, when you're prone to feeling especially lazy. You don't have to hold the DS Lite up just to be able to see the second screen: it's held up for you, and at the angle you want.
The only real complaint I've got is that the detachable black plastic & foam covers can be pushed out from the back pretty easily, or can even slide out with enough forward-moving pressure (even with the tabs that keep it in place). That, and it doesn't really transmit vibrations from the Rumble Pak, though that's more an issue of the strength of the vibration.
Overall, though, I'm pretty glad I got it.
