haha, calm down mate! I am neither cribbing nor complaining. Being a discussuion forum, I would like to discuss my views and get feedback. I am trying to learn more than simple programs that anyone can do after a while. Discussions help you in learning something new from someone. And I wasn't rude either! Please make sure to not make such comments, this forum is just for discussing and that's what I too believe in.

All these apart, from what you have said "A programmer's responsibility is to consider the system for which s/he is coding." It seems that you have no or very less practical experience in developing applications for various platforms. I remember days I struggled because of someone else's such coding approach. Nothing is easy in initial phases, and at least for me it is not a nightmare to write a code that works for multiple systems. Moreover, currently and for quite a long while smartphones rule the world in terms of business. This demands you to develop applications for popular platforms, you shouldn't be wasting time in re-writing code for every system you have out there.
