The .mobi top-level domain is not without critics. It's goal is to create a place for separate mobile-friendly websites under .mobi. Critics will quickly point at the available technology for creating single websites that adapts its presentation to the type of device that is used to visit it (semantic html + css). If you want to see that in action, just visit http://www.goodwebhosting.info with your internet-enabled mobile phone. Same site, just mobile-friendly presentation in a separate stylesheet.

More information available at domain registrars everywhere and the dotMobi registry. I find it amusing that the current link the latest dotMobi news points to a Word document. That's definitely not mobile-friendly ;-) And they have a mobile-friendly stylesheet too.

Go to your favorite domain registrar now if you really really want some good .mobi domains. General registration begins october 11th.
