I want this device because it is currently the only "no-nonsense OS" for serious users and I would like to use it for everything that I would normally do on a full blown OS for the mobile like Windows 10 Mobile. Have tried my hands on Android, FireFox, iOS, Palm as well as BlackBerry OS 10 and that is in the "best stability/efficiency of use" order with BB leading the pack. The closest anything came to being that stable is the new Windows 10 Mobile and this beast of a device Lumia 950 XL.
