I modded up Chriskagunda's post because I think it clearly illustrates why W10 mobile has an increasingly limited future; the death of apps.
If I used my cell to only make and take calls, I'd probably be using my old flip phone and would have saved a good deal of money in the process. Like others however, I saw a mobile future for the cellular phone that I was anxious to embrace.
The app debacle was created in part by MS by their foot-dragging approach to early SDK support and then furthered by their app-killing updates. On the public relations side, they haven't fostered a strong relationship with app developers either large or small. Over just the last few years, I have watched banks, brokerages, and retail outlets drop support for their W10 mobile apps as well as watching alternative browsers and other apps disappear in the face of various issues not the least of which is a declining user base. I am painfully aware of being told, "Just download the app." and having to reply that there isn't one for a W10 mobile cell phone. That's doubly galling when "they" used to have a Windows app that I used, but no longer and have refined the app for iOS or Android.
