Personally, I think .tel is a much better term for an extension than .mobi, and I wish they had launched it instead of .mobi as a full-fledged TLD in the first place. Mobi is a made up term, whereas people have been putting Tel: on their business cards for decades.
But .Tel is not the same product as other TLDs. Right now, you can only have a single template that lives on their DNS, no development allowed. It's an entire TLD that serves no other purpose than to be an overpriced, overcomplicated, incomplete phone book.
Think about it. How much chance would print phone books have had if they charged each phone number holder $15 just to be listed? None at all, because they would have started with zero listings and never been able to build momentum because no one would use such an incomplete product. The phone book business model is to give away the listings for free so they have a complete useful product, then sell enhanced listings and ads.
.Tel is a solution looking for a problem.
So I have a hunch that the rules for .tel will change once the concept falls flat. Like any startup they might try to change their business model.
Perhaps the change that will come to .Tel is to give the listings away for free, then sell ads on peoples personal contact pages. But that service is already offered on countless online phonebooks.
If the concept fails, then I think it is just as likely they will open up the DNS for transfers and full development.
There is precident for changing the rules of a TLD: .Org was originally only for non-profits, and you had to prove your status to get the ext. That rule changed, and it is now available for anyone to register. Granted, .tel's entire framework would have to be changed, not just a registration rule. But if the alternative is bankruptcy, I think anything's possible.
I think digital is a great word, so if I owned it I would do some research into this possibility and actually hold on to it rather than flip it for a few bucks.
That said, I haven't registered any and don't plan to. Perhaps I'll miss the boat on another ext launch -- I wish I had been fonder of .info when it first launched. Or perhaps I'll save a load of cash by sitting it out. I keep looking into the future, perhaps the very near future, when several hundred new tld's are launched.
Just another random opinion, worth as much as the electrons its imprinted on.
