1 - KEY: It is the single most secure mobile operating system. Should search up some Black Hat Defcon commentary on just how hard it is to crack. The most poignant comment was "without physical access to the device [Windows phone] I wouldn't even bother trying"
2 - System gets regular updates from the OS maker - rules out 99% of the Android market
3 - I can customize my homescreen and see upcoming meetings and their locations quickly. Customization and the ability to pin almost anything, any setting or link to the homescreen is big. But this has to come with updates from the OS maker, so only Nexus or Apple.
4 - I can pin individual mailboxes to the home screen so that counters for important things are dealt with quickly but also so that less important mail that streams in all the time doesn't cause me to "look" all the time. Apple can do part of this with two mail programs but you still can't individually track two mail boxes inside the same mail account separately from a glance at the home screen.
5 - I can connect with any Miracast device. I don't "need" Apple TV. Only need that if it's the right tool for the job and I think it is not.
6 - Wireless charging and fast charging are game changing even with big batteries.
7 - A real file system, that with a plug of a USB cable I can access, rearrange or drop files into my phone at need.
8 - A very good camera (for its kind). Despite having a plethora of SLR gear to choose from, it is the camera that is on you that trumps all the stuff in the closet. And I almost never, ever use a flash so OIS is very highly appreciated.
9 - A dark background OS. Sorry but the fruit crew literally haven't given up on the day glo colors from the 1980's. I think it's a cute tribute to Jobs' history, but they need to notice the number of phones that come in black today. I don't need white backgrounds and bright screens. The Windows OS is much more refined. Oh and the consistency of the interface compared to Nexus, even if they did break that a bit to add features in Mobile 10, is much smarter. Dev's comment this same consistency helps in making apps too.
10 - Big and little. I can alter the importance of an icon on my home screen. Calendar and phone are big, hit it fast icons, where I could care very little about others but still need them on the homescreen for that once in a while moment.
11 - A browser that works. Safari is not bad, but not good either. Chrome is ok, not great but ok. Since I don't use Chrome at all on the desktop (ever), Win 10 mobile gains me synching favorites as well. Handy. And why oh why can't Apple figure out or at least offer the option to put the browser tools at the bottom? Win 10 Mobile manages this. 25% bonus score for just being intelligent.
12 - Back and search. I can't tell you how many times the back button has saved me and the long back to sift through apps is again, crazy useful as I open a lot of stuff and leave it hanging. A search button? Again, Apple couldn't figure out how to make it look good so they didn't use it. Priority for Apple is looking good. Usefulness comes somewhere 3rd or 4th I think. 2nd is can they sell you an accessory to go with the feature.
13 - OLED. Not on all devices but it's on most of them. Apple = zero Nexus 2016 = zero
14 - apps has what I want, Office, Skype and Skype for Business, BoA, Fidelity, Etrade, Runtastic, Pandora, GoToMeeting/Webex, even Cnet and Bloomberg and AnyConnect. The browser (because it is a good one) connects to all else I need and that's about it.
Apple competes but it's less useful to me. I don't need unsecure home security apps, that's what professionals are for. Sure having some things like FIOS apps would be nice, but honestly would I use that on my phone? No not really. I think we go into a phone store with glittery eyes, looking at all the "look what you can do" and in the end, day after day, the things you actually do don't involve 1% of all those could do things. If I was truly missing something from another platform (feel free to suggest below but I've not found a thing yet) I could switch. I have to use all the OS's to stay versed in what others use and help them with their devices. But Windows is faster, more time efficient and less wasteful of resources and time for me. Apple would be my 2nd just because of updates and better security. Due to security issues that just never end, Android would be my bottom last choice, pretty much only if there was no other kind of phone.
There you are
