I've never heard of the show, but those are some huge viewership numbers

I think that the "kids" (say those < 20 today) just may be the ones to adopt and create .mobi. If I take myself for example, I was just a child in the mid-1980s when .com came out. By the time I had grown old enough and knowledgeable enough to reg .coms, most of them were gone. If we look at most of the "good domainers", the ones who got in say pre-1995, most of them are a generation older than your average internet user (if we negate the few 70+ users that skew the statistics). I could see the same here. I'm a generation older than the average text messager (is that what they're called?), the average cell phone junkie, etc. Matter of fact, I've went my whole life without a cell phone. I was old enough by the time they caught on (say ~ year 1999-2000) mainstream in Canada, that I just had no interest in them. There's a scant few people I know my age who do use their phone for "texting", but most of us regard it as childish. On the other hand, those young adults and teens seem like they can't get enough of it -- and I think that should be .mobis primary target market.
I'll probably never get a cell phone (and certainly not for any purpose other than business, should that need arise), nor will I ever use .mobi on one. But I, like many others here, certainly see a future for the mobile internet. It just "makes sense" for this younger generation. And 10-20 years from now, my generation will be starting to retire, and these "kids" will be the real movers and shakers... These will be the guys running Fortune 500 companies and making critical business decisions... Hook them on .mobi while they're young and impressionable.
