Awesome!
I happen to HAVE a PalmTreo PDA thats has internet access, and I carry it wherever I go. .MOBI is global, most people in third world countries don't have a desktop they have a cellphone!
Now with that said, the internet is not about only going to google.com or google.mobi, its about going to mom and pops site, a free platform for all, for budding sites (freedom); unfortunately, If you have a PDA you know, most of these valuable mom and pop sites are NOT optimized for the PDA screen with wap2.0 etc. With .mobi it is more power to the people because they know it fits on the PDA screen!
I know some phone carriers were against it but don't you know that they have a business interest to say so! They want you to keep paying for phone calls whereas the internet, boosted by .mobi and the evolving of phones to PDA's, has the capability to make phone calls for free eventually! The phone carriers will become ISP's! Of course all the cell phone MANUFACTURERS are all for it!
Remember cellphones (and .mobi) are global, travel to Africa and Asian and Latin American countries and know most people don't have a computer for many reasons! IT's all about the cellphone evolving to PDA and naturally getting cheaper. The internet is for all 6 billion people, so don't just look around where you live and judge the .mobi; remember these are all your potential customers.
