I used a windows 7.5 phone before that I thought worked pretty well and always thought it seemed pretty snappy so overall i liked what windows offered. Im currently on a samsung s4 that works fine for what I do,mainly social media apps, no gaming. I do like taking pictures and have built up a very expensive dslr kit that stays at home more than i would like but of course my phone is with me everywhere. So quality pictures from the phone is a big plus. I dont need to upgrade or switch phones but I am interested in whats out there. So are there any thoughts about windows ecosystem? Thanks
