I wonder why they're complaining about the system not having a usb/mini-usb connector? Don't they know that you can get a DSi(and 3DS by default) connector to usb charging cable? It's a cable that has the DSi connector on one end and a usb connector on the other end. I've seen them for like 600yen around here. (The DSi and 3DS have the same connector.)
I picked mine up for very cheap though. It was a bundle on clearance that included a DSi Silicon cover, a 2gb SD card and the DSi->usb charging cable for 500yen. 
That cable also lets me use my Dsi/3DS with my Eneloop Stick Charger for emergency charging, as it has a usb connector. (I bought it to use with my iphone)
