Still confused ! when my close friend told me to install imo to talk (since he is having issue with skype), I couldn't find the app its frustrating. when my aunt wants to video chat with viber, i am have to say i have no video calling feature since i use wp, it hurts. there is no close substiute of google voice, very useful for free calling (remember skype charges 4.9 cents connection fee+2.3 cents per minute to call to us no from us !), nothing is better than gmaps, nothing is better than gmail. I love windows phone, but this love has a lot of pains...still using lumia 920, also used 1520 before. windows need good phone plus good featured apps not half-baked apps,even skype works better in android, i get notification one day later in wp sometime. i live wp but its better to admit its flaws which are plenty. Enjoy the fluid OS, better battery performance, and most importanlty, wp keyboard is my favorite, the word flow is awesome. I am not sure whether I would buy an expensive phone from windows but I will always carry wp phone, may be I will be getting an android as back up. iOS ? I don't see why should I pay that much, any phone under 100 can perform as good as iphone. so windows is my love, android is my reality, ios is nowhere !
