Well, now that I moved, I at least see why she was hoping I had my tools... among other reasons, because the case on her original ds, and a friend's ds lite would likely need repair/replacement. The DS lite's hinge practically completely broke off, and the original DS has some screen issues in addition. I wouldn't be surprised if the original DS has simply had it.
I just wish Nintendo would have fucking addressed the problem with the DS lite and all the hinge and button issues properly. It was not fun having to return and replace 8 of those from my own personal use. In that sense, I'd been grateful that my 3DS has been sturdy, but even it looks like it'll need a new shell too... main thing is that the camera facing me has a noticeable scratch that impedes the ability to take a proper picture. Not sure what I can do there... or if I should bother, since the DS's have all been awful for any actual photography.
