I think that the problem is that, from a totally non-technical person's standpoint, it's really no different than the DS Lite (camera aside). Gamers like US know about DSiWare and DSi Store, SD Card integration and all that, but the average Joe will surely look at the DSi and say, "$180 for what? How is this different from/better than the DS Lite?"
Dare I say that the DSi almost reminds of the PS3 and PSP in the sense that it has several new features that tech nerds cream over, but mean nothing to the average person.
My router at home supports WPA/WPA2, so I'll fool around with the settings. Thanks for the heads-up, Shecky.
