khim, can you just give it a rest now? By now we all got your point, and it seems you just can never leave the last word to others. We know you opinion, others are entitled to other opinions. And why should companies such as Telefonica or Deutsche Telekom not be allowed to experiment with alternatives to Android/Windows/iOS ? Following your arguments, one would never have started Linux in 1991 when there were so many established platforms around. And even if B2G fails, but leads to an improved Gecko engine through that, it would be a success in my book. So relax, lean back and see what happens. You can still pull up the "I told you so" card in a few years....
