First of all I would like to appreciate what you have mentioned above. Your caption tells me how complicated you are. " It is so simple to be happy,but it is so difficult to be simple". Majority of the people find it so easy to be simple but very difficult to be happy. This is a forum to ask help and discuss many concepts and not a place where every word needs to be complicated. Make it feels better when its not complicated! Anyways appreciating your point of view.
Coming to my project, I have planned to build on my own. So I am in the process of collecting data of all available low cost applications. My target is to make it possible within $100. I would like few suggestions from people on proceeding with this project.
