Hi. I would like to know the main differences between Android and windows because I want to go for one of the two but don't know much about the two OS. Please answer me these questions. a) Can I download Apps and games from Google play store using a windows phone? b) Is it possible to share Apps and games using Flash share between a person with Android and the other with windows phone? c) in brief what is the advantage and disadvantage of each of the two operating systems?
