For some weird reason, when I saw this picture, I thought it looked like a robot invasion consisting of small white standing slimline gadgets... You can easily see where they would shoot their laserbeams from...

this would be a reasonable solution for adding a WEP network to allow the DS to get online in my otherwise WPA-2 encrypted network. If it only allowed connection Nintendo Wifi and only allowed DS/Wii clients, that is.
Not that redundant for people who just want to get their Wii online, and want to buy something they KNOW will work without any set-up hassles. Both Wii and DS can be fussy about their wireless routers, like other such devices.
