Loving windows 10 mobile!!

I'd actually like the OS if they brought back history and notifications for contacts. But so far there is no indication of such. They gutted the people app of its most useful functions to make round pictures.

Other nice to haves would be:
  • A UI better optimized for mobile (like 8.1). In making Continuum they seemed to forget it should be a mobile device first.
  • A photo viewer that doesn't take an eternity to load new images (even slow in Win 10 desktop).
  • Ability to select photos by folder.
  • Better use of theming. Theming took a few steps backwards in WP 10.

Having made extensive use of both versions I find 8.1 a lot more consistent, fluid and has that just works feeling. Windows Phone 10 feels a bit more android like in some ways without having the benefits of being android.

My favorite things in WP 10 is the native weather app and the action center improvements. The deep skype integration is also something I'm looking forward to.
 
I really don't know what to think about microsoft team. I own lumia 640 with the latest w10m build, but also use w10 on my laptop.
Both were "factory reset", no backups, no restoring- fresh OS. I wouldn't expect w10m to be perfectly polished as this is only preview, but I expect it from my laptop. So the problem is that I can see similar issues in my both devices which could mean that it doesn't metter if it's a preview or final OS, Microsoft didn't realise that changing from win8.1 to w10m (w10) will take so much time.
And I must say that I really love the new UI of w10m/w10 it give windows users so much more possibilities, especially to mobile users. Now I know that I will not switch to any other platform, but I really would like to see more improvements/new builds more frequently, so I know that they try!!!!
 
One more thing- I already reverted to mobile 8.1 twice as there was too many hiccougs on previous builds, but this time I really feel like there is closer to the final version? what do you think?
