But i do not understand one thing.
Samsung uses the same hardware for both phones (almost, except screen size) as you said, DA. For the Wave, it develops its own Bada OS, thus incurring the development cost of an OS. In the case of the GS, it uses Google's (OHA's) readily available operating system after applying some custom tweaks, interface etc...
Then in this case, why is the GS priced at 11k (28k vs 17k launch price as you said) more than the Wave? Should the 'development and maintenance cost of a new OS, plus maintaining a market' of Wave/Bada not cancel out the 'extra screen cost and tweaking cost' of the GS, and thus leading to similar pricing of both phones?
Nokia CEO Stephen Elop had said a few months ago that though Nokia will pay Microsoft for each copy of WP7, still the cost of the phone will be lower than that of a similar Symbian one because Nokia's OS development cost for Symbian will be saved.
In Samsung's case, they do not even have to pay this cost to Google since Android is free, open source.
Then why is there so much difference in the price of Wave and SGS? A much lower profit margin?
