As others have noted, there's mobile TV here in major markets as well (MediaFlo - if I have the spelling right). I'll pass on the smells, thanks.
For "MacBookPro" yes, I've spent time over there and used the devices. You're obviously impressed, that's great. I'm not.
Are they cool? Sure.
Are they suitable for other markets? Not so much. So, go ahead and spew yourself, but bottom line none of those devices have made it to the US or are going to make it to the US. Even if they did, I think you'd likely be surprised at the response to them.
Speaking of networks (as opposed to devices) - while they do operate in a smaller _and_ more dense environment than in US, they also spend a crapload more on equipment and backhaul plus operations staff. They've very very exact in what they do.
From first-hand experience, I can say that the Japanese operators that I've dealt with are heads and shoulders above Verizon as far as operational excellence goes - and there's no comparison against AT&T based on my iPhone experience.
