Of course it is ICANN's and business after .mobi scam. However if .mobi works in the future will do only because perhaps big telecoms companys after .mobi consortium will do something to give priority to .mobi domains in their devices. I mean Vodafone, Movistar, Google, Ericsson, Microsoft, T-Mobile or Nokia -just some of the companies after .mobi- will agree to give priority in their devices to .mobi when you enter a word in their browsers just like now happens with .com by defect in some browsers or toolbars.
