VI IV may mislead you to think "64-bit", but it does not even run on 64-bit operating systems- only on 32-bit XP Media Center Edition and Vista Home Premium or Ultimate. As I found out the hard way after buiding a system with a so-called VIIV-ready motherboard and installing 64-bit Vista on it.

I actually saw a Viiv demo or two at all three of the IDF's this year. I don't think its dead yet.

... wasn't this the idea of a small, silent computer to use as a DVD player, PVR, etc.? 

Uh, yeah, sorry. I bought one of those tiny Apple boxes to do that stuff. Ooops. My bad. Well, it looked nicer, without all those stickers on the casing.

It surely is an embarassment, and don't call me Shirley...

Hardly!

So...VIIV would be what then? I just figured it was "VI" = 6 and "IV" = 4 so this was Intel64. 
Which, granted, even AMD64 hasn't done anything memorable so far.

I'm friends with an Intel rep in my area who's pretty gung-ho about his company. When VIIV was first unveiled, I bet him that in a year we'd be sharing a big laugh about what a terrible idea VIIV was. 
I think it took slightly longer than a year, but that day has come, as expected.
