I really love my windows phone, I had a lot of them, from the LG C900 (win7) to the Lumia 1520, now i'm rolling with the Lumia 530 (no problems). I'm an aspiring programmer, and I've seen that the Store is a little lacking, maybe I can be of some help, and boost the ecosystem in the future, so I'll use the Lumia 950 XL as a development device.
