Its a catchy domain ONLY if mobi really takes off in terms of real use and not just in selling domains, you gotta accept someone's opinion if they think something is not worth it at the moment, if you really think this domain and other mobis have a bright future do something about it and create some websites that make sense for mobile use, next time someone tells you its worth $x.xxx or even more, ask them to make a real offer in $$$$ right now and see what they say..very quickly you will see that its all talk...
