NTT DoCoMo is currently working on a cellphone that delivers block rockin' ringtones in 5.1 surround sound. Why would somebody ever want 5.1 on a cellphone? Well the real question is why wouldn't somebody want 5.1 on a cellphone?
Okay, this has a little more application overseas where the DMB television runs free on cellphones, but still, wouldn't regular stereo sound be sufficient? That is bound to suck the battery dry in addition to annoying everyone on the train. This prototype phone is currently on display at CEATAC.
