I have a L1520 with Windows 10... Why would I want a 950/XL? Continuum? No, it's great but I would never use it. AMOLED? No, IPS LCD is better IMO. There is no reason to move from a 1520 to that, the build quality is below par, the over design is just an insult and watching some videos on YouTube shows that in most cases the 1520 is the same speed and in a few cases actually quicker (when starting up, opening apps, camera etc.) than the 950XL. On another personal note, I prefer the bigger phone that the 1520 is, I know most people don't like the massive size but I do so dropping .3 of an inch and having to pay for it is just a no no. The 1520 is no slower, has a bigger and better screen and is far more nicer looking.
