I know people around me switched from Android with my advice and they are very happy about windows phone, in the beginning few of them scared about lack of apps but when they jumped they understand there are alternatives for some apps and others are not very needed so they didn't feel upset.
What they noticed about windows phones:
* Many features built right into OS or bundled with the phone so no need to install app for it ( word flow keyboard,double tap to sleep/wake,skype,health and fitness,here drive and maps,weather,facebook,twitter,microsoft office........)
* The Os feels more modern,smooth,lag free, virus free and phone will not slow down after time or suffer from memory problems.
* No need to buy high specs phone every few months because phone will stay smooth and fast like day one so no need for new hardware to enjoy speed or features of newer OS versions.
* Updates are continuous and free, Which of android phones will get new OS updates after more than 2 years? Lumia 920 which released in November 2012 still get updates and will be updated to windows mobile 10

* Battery life is better, for example HTC One M8 runs Windows phone has longer battery life than same phone which runs Android!
* Good camera and very good apps to process photos.
* excursive Nokia technologies like clear black display, glance screen,pureview cameras........
I can go on and say many other reasons that made these people love Windows Phone more than Android

I've friend who owns samsung glaxy note 3 saw me recommends Lumia for another friend and he said to this friend ( don't listen to him go with Android it is better!) immediately I asked him( how many times your flagship phone slows down or stop to work last week? ) he admitted it and said (I can't count it it is normal thing in phones

) for his surprise I asked another friend who owns Lumia 535 the same exact question and he said (I don't remember this ever happed to me )
My advice if you feel you want to go with windows phone just do it and enjoy, don't listen to people.
Buy Lumia 640 XL in the beginning, it is not expensive phone and has good battery life and good big screen.
Regards
