My Lumia 950 is my only phone, and I'm an insider on the fast ring. I make use of it quite a lot. I'm a senior software developer for a good sized company, and I use a lot of business related applications on the phone. My most used apps include Word, Excel, and Powerpoint on occasion; OneNote very often; To-do list; Skype (for text/mms messaging); Skype for Business; Slack; Groove music; an FM Radio app on occasion; Edge; LinPhone (Voip app); Outlook Mail (configured with both personal and work accounts), Calendar, People; Twitter; Facebook & Messenger, Instagram; Maps, Weather, News, Echo radar, Okta Verification.
There are also a number lesser used apps that I have on my phone that are occasionally used.
I hate playing games on my phone, with the exception of an occasional round of Wordament.
I do own a couple USB-C "docks", one by TNP that has USB, HDB, and Ethernet, and a second from Aukey that has HDBI and 4 USB ports. I also have a Bluetooth mouse, and the Microsoft Bluetooth foldable keyboard, and I do use continuum on occasion at work, and a lot more when travelling when I can connect to a TV via hdmi. Although I usually have a laptop with me when I travel, I am trying to use the phone more as a primary device.
I do use Cortana for setting reminders, checking my calendar, and even getting package tracking info or flight status info.
I also keep a 15,000 mah battery in my backpack in case I ever need to charge up my phone on the run.
My spouse has a Galaxy S7, and I have friends with both android and iphones, and I have to say, I really dislike both of those platforms. Windows phone is just much easier to use, more friendly, and really more capable in general. Now if only more app developers would start building UWP apps.... but there really are a lot of UWP apps out there now.
