Maybe you know the deal with 1seg, but in case you don't, it's Japan's new(ish) native-brewed broadcast digital TV service technology that devices like the PSP -- and now the Nintendo DS -- are rocking. Granted, we can't help but thinking the way this cartridge is going to jut out the back of one's DS is hardly elegant compared to Sony's much more densely designed solution, but the Japanese obsession with the DS knows no bounds, so godspeed, 'Tendo. This dongle will sell for ¥6800 (about $60 USD) when it goes on sale in Japan on November 20th.
