Before I boarded the Samsung ship I had 2 Lumia 920's. I really, really loved Windows Phone despite the lack of apps. Unfortunately both Lumias were defective one way or another and after 2 swaps I just switched to an S3. I would try Windows Phone again if I could find all the apps I use or some equivalent. Maybe not the 950/950XL though because they look SO bad. Like, not ugly but just plain and boring. Like holy crap, whoever designed these things literally managed to make $600 phones look like $200 dollar ones.
It's a shame because the software is SO smooth and stylish otherwise, it's a real contradiction. If you don't mind the look I say it's worth a shot, especially considering how power-hungry and bloated Android is becoming. Let's hope Windows Phone proves to be still as efficient as iOS like it has in the past.
