I am still using a 950 XL, and for the most part it still works well. Just a couple of months ago I had gone for a holiday where I was able to survive by only carrying this one device. The battery life, mostly due to the processor, is a bit weak, but otherwise the display feels gorgeous as ever.
Coming back to the holiday - the 19MP camera on this is still a beast! Granted that photos in auto mode don't away work out, but I have become so used to the manual mode! With the level of detail and light I got in sunset and landscape pictures, the quality felt way above the average smartphone (as good as a point and shoot for certain). I love taking pictures, so the processing times got on my nerves a lot, but the results were worth it. Overall in the trip I ended up clicking about 1100 pictures in a span of 8 days (this count contains bad / double shots of course).
Having wifi in my apartment meant my pictures got backed up to OneDrive daily, allowing me to clear a lot of the space (specially deleting huge video / pictures for timelapses).
With continuum I would connect to the TV and review the pictures I took, check my emails, do a bit of expense tracking on excel, did web browsing, skype calling the family and even watched movies I had on my USB drive.
The convenience of it all was wonderful. I have a feeling I will miss continuum when I do switch to android.. Samsung has it, but I am not a big fan of Samsung's overall software execution on phone. May be one day Google will decide to make it an OS wide feature.
OR Andromeda will be useable as a phone and I won't have to switch to android after all
PS - currently, the lack of many options for a big camera sensor on phones is my biggest roadblock for switching to Android. Sony is probably the only good one with a big 20MP sensor, and Oneplus with 16MP, but they both seem to leave something to be desired
