Very sad
Windows Phone 7.5 was the best version imo, but even windows 10 mobile isn't bad.
My biggest gripe is not being able to restore a backup on demand, and a restore that doesn't work most of the time, because it doesn't know it should upgrade 8.1 to 10 first, then start the restore process.
Apart from that I still intend to use my my Lumia 930 as long as battery will allow, as it is a darn good phone and I do not need snapchat or any other similar piece of crap.
