Context: Started with HD2 with WM and after flashed with WP7.1, after I passed to Lumia 920 and now I own a L950. All my working environment is based on PC's with Windows OS (7, 8.1 and 10) + MSDNAA+Office365 Education (where I'm also admin).
Why? I want to use it as intense as possible the compatibility of the windows ecosystem with my working (university) environment
What I'd do with it? I'd like to make this L950XL as my working phone trying to exploit its potential with Continuum for my teaching activities (presentations, office applications so on), remote desktop usage and another remote applications, Skype for Business usage. The camera potential I'd like to use it also for my daily academic needs.
