What Could Be Happening
Many corporations could be registering the mobis simply as a precautionary measure in case the mobis become widely accepted and used. What's $10 to any company?
Nevertheless, no other TLD since the .com has generated this kind of "preventative" registration, IMHO. It is clear that businesses are jumping on board in record numbers. The only question left is will the general public jump on board, too?
For a while there, I was wishy washy in my mobi expectations. Yesterday, however, I was shopping at a Fry's Electronics when I happened upon their Sprint, MetroPCS, and other wireless vendors' displays of hand-helds. There were several units that had decent-sized screens and mini-keyboards. I didn't need one, but I surely wanted one.
The question I keep asking myself is will I surf .mobi or .com sites with it, or both? If I just wanted to type in the domain name in the browser, I'd probably be confident about the .mobis because of their compliance nature. If I used a search engine, it's apparently obvious to me that "mobile compliant" will eventually be in every search engine results of a particular domain, so I'd just click on the web site, be it .mobi or .com.
Perhaps .mobis will be accepted for a while, but sooner or later .com sites will add code to make their individual sites viewable on both screens. Just look at how quickly webmasters added meta tags and other codes. It will happen.
On a final note, one saving grace of the mobi is its ability to become a global TLD, bringing together all country code TLDs under one mobile umbrella. Add to that a .mobi button on hand-helds, and both the users and webmasters will have two good reasons to go mobi.
