The difference between the GB and the DS is the touch screen, otherwise I'd agree. The closing mechanism certainly aided in mobility, but its primary function is to protect the touch screen. I mean, it'll probably be okay, but my siblings go through DS's every year because their bottom screens get so gouged out that they're unusuable (at one point my sister decided a fork was a suitable replacement stylus...)
I've seen similar damage on other people's devices, even adults.
