Mentioned it in my non-gaming related online diary. I basically said Nintendo's new system is called Wii, I want to know what people who haven't already heard it think, and I included a link to the animation on Nintendo's site.
One person thought it was dumb but didn't care too much. The other person thought it was okay, but sounded a bit too much like a "try-hard" marketer name. You know, I think she may have read the whole spiel that came with the animation, I personally found the explanation of the name cheesy and full of marketese. "It's not about you or me, it's about Wii." I find stuff like that insulting to my intelligence: it's obviously marketers making too much out of a name.
I also mentioned it casually to my family. Something like, "So, Nintendo's new system has a name...it's Wii." I hesitated a bit, may have sounded kind of unsure about it. My mom had no reaction, my dad was like, "... ... ... Well, that's okay, it's definitely not like anything else."
So I'd say I've got one mildly positive, one indifferent and one mildly negative.
For the record my initial reaction was, "What?", then, "Man, that's fruity, but interesting, I wonder what everyone else thinks?" My first reaction to the explanation was, "ARGH! Okay, I get some of the logic behind it, but please shut up with the quasi-inspirational marketing crap."
