I much preferred win 8.1 on my 640. Real fast and mostly even looking OS and everything seemed to work pretty well. Here drive worked okay. Win 10 mobile for me was/is slower, some things are small text'd and hard to read and it doesn't look as good, there are numbers which should be names in an app listing in some part that everyone has and never gets fixed...the email app was less easy to use...
