lol. one month is very little time to see the value of a smartphone i personally believe. i usually get bored of a new phone without a period of one week myself. of course, some people are able to extract more value out of a product like this compared to others. but i would not suggest selling it unless you are absolutely sure that you do not plan to get another smartphone for another couple of years.
Heh, if someone having 5 phones including S2 is thinking of getting a Tab2 (considering he is not earning yet) and then is thinking about "throwing" away an S2 will bother about the price of an iphone? Also as I said, for some its all about looking cool than getting something that is useful. Windows, may not be cool, but it may be a way to be different from the Android & Apple crowd.
