Ashu must be running out of subjects to crank on the forum to pose a rhetorical question like this. Itýs insulting to the intelligence. We all have our own theories on why the system didnýt work. Ask anyone and you will get earful of answers on this subject. Why donýt do the community a service and tell us your views, inside stories, new discoveries that you have made rather than asking mundame questions when you already know the answers.
