What's really bad about Windows Phone? There seems to be no way to backup your phone on your desktop. If you don't have data plan and you don't frequently connect to Wi-Fi, be prepared for Loss Of Data. Lost all my contacts. Thank you Microsoft.
Changing all my phones to Android Powered Smart Phones. Yeh, people say it has security problems, but the truth is I have not seen any of my friend complaining about their Android powered phones in last 4-5 years. Heard a lot, about issues on Lumia range though.
Another good reason to switch to Android is Android phones are relatively in-expensive and it's an important factor too. Secondly there are many models available to choose from. App availability wise also it beats Windows Phone.
