I don't consider myself an windows phone/windows mobile addict. But having been accustomed with the good and the bad in the windows ecosystem for several decades, has made my adoption of a windows phone device a relatively painless chioce to go for. Windows Phone has thus far fit my work and personal flow since windows mobile 6.x.
I currently own and use a 1520 and 950XL. My 1520 battery died after 4 years, but I repaired the phone with a new battery, and it currently works like new and is happily running windows 10 mobile (Thanks Microsoft!). I use my 950XL as my daily driver and my 1520 as my back-up device.
In the early days of windows phone 7 I had a HTC x310e and a galaxy note first gen. I loved both devices to bits. But the interesting experience for me is that I gravitated towards windows phone more after several months of using both devices. Android was increasingly alienating for me as I found it quite difficult to integrate the device in my workflow with windows, despite loving the stylus functionality. Android, for me was too problematic get the syncing and updating right. The skewed app choice that was less compatible with windows was a problem, as it forced me to use the device as a standalone device. I had this issue less with the HTC. Also the two wonderful designs of hub apps and live tiles, made the OS wonderful and easy to use. Microsoft's pitch for "putting people first" and the "get in, get out, get things done" with the OS worked perfectly for me. With android I just got lost with what seems endless tweaking of the phone and the OS to get it to work for me. Samsung's OS+ android wasn't working for me, it was the other way around. I found myself wishing, if only windows phone was on here with stylus support, it would be great! I found my choice! I was happy!
This continued with the 1520 and 950XL. My 1520 was awsome for my big hands, a great big 6 inch screen for awesome reading and a great camera. I would have used my 1520 longer, but I was stuck with a failing battery and in an emergency to have a new phone, because my 1520 battery was failing I bought a 950XL roughly six months after official release. I didn't have the time to wait for the phone repair. I was suprised that the 950XL worked better than what I read on dreadful blog reviews. But I noticed microsoft did a huge job to make the phone work great on this device. The camera was slightly better, to my surprise than my lumia 1520, I adored the oled screen, it was snappy, and I was surprised how better continuum was than on my 1520. It felt like a pc on my phone projected on a larger screen!
I use my 950XL intensively for work and private use. It's a great and snappy device. The store choice of apps is enough for me. Because I work in healthcare I was hoping to see more android apps, but that remains a disappointment.
I think the UI and live tiles are still a forte over android to use on a daily basis. Not sure how to explain it, but it just works for me, the glanceable information, the customazability on the startscreen, live tile folders, the actionable tiles, the free maps and navigation with windows maps and navigation work great in everyday use for multiple visits. Just save your route as a live tile. The next time just press the icon and hey presto, done, you're on your way. Awesome!
With my android gingerbread OS I had the unfortuante experience of unwanted apps and crapware being installed on my phone and the necessity of likely having to install an actual virus scanner to keep my phone up to par with security. I always found that a weird experience for a smartphone, and I didn't like the prospect of dealing with it on a mobile device. With windows phone I've always felt safe. I never had the sense I had to concern myself over safety above the security that was already available and in place on the phone. I have thusfar never had a bad security experience with windows phone, which has increase my trust in the platform over android. I don't know how it is in 2017 and if I would think differently if I used android or iOS now.
I have tinkered with windows mobile and windows phone 7 ROMs for a little while via XDA for a little while. Maybe I was a bit addicted then on the platform. But the results of the tinkering never really satisfied me, because most ROMs and executables never were really stable enough for realworld daily use and didn't offer a better experience than what I already had. In that regard I'm happy windows 10 mobile came around, in which even the phone was updatable to a new OS update. It felt like a breath of fresh air when I experienced this the first time on windows phone.
I'm sad to see windows 10 mobile in maintenance mode. I still use both devices. Oddly, both are still improving in time with performance and stability, which is a great experience. Despite the mainstream remarks of windows phone being "dead", the experience, for me, is still damn nice.
Four things I would still like to see happen is:
1. more live tile functionality and customizability.
2. landscape mode for the start screen.
3. continuum with at least two apps that I can open side by side. ( I think windows 10 mobile is then for me a viable option to use as a true pc on my mobile and be productive. Now with one app open at a time on the screen is a little counterproductive in real world use)
4. More UWP app support in continuum.
I think if these 4 points were addressed in the last 12 months, I think windows 10 mobile would still be a great potential and recommendable for daily use today on a windows phone or oem smartphone device.
