to be honest i kind of feel it too. i'm not microsoft big fan by any means but i get what you mean. in fact i feel like it's pointless to buy a new windows phone at this point. I had high expectation when WP8 came out, i love my lumia phone, but as time goes by, i realized most of the services in WP you can also find them in android. I believed it was cool to have full offline navigation with Here Drive and Here Maps but now these apps also exist on android. Onedrive, office, onenote, and outlook are also available on android and so I said to myself what's so exclusive about windows phone anymore...to be very honest, i have assumption that WP is inferior in almost every way to android at this point except for the camera but camera is hardware issues and im sure there are decent android camera phones as well (i dont take a lot of pictures so I dont care much about the camera tbh). the only another thing I can think of is malware/virus but considering i might not use my phone much, i dont think it should be an issue as i dont browse to random sites from my phone. as for lag issues, high performance android phones like oneplus one is smooth enough to me (yes my friend has it and i have tested it).
The first time i bought my lumia, i could easily say it outperform most android phones, maybe except the most expensive ones. nowadays there are cheap android phones that can go toe to toe with lumia, like oneplus one, xiaomi mi4, and nexus 6, they are actually cheaper than flagship lumia phones. Considering the pros and cons, tbh i dont find much "pros" in lumia compared to those fast android phones.
I do love microsoft services. I have android phone myself but i still use onedrive, onenote, office in my android. My laptop is windows 8.1 and ofc i also use microsoft cloud services here on my laptop as well. but again, i dont see much future in WP tbh. I dont see the point of buying new WP device anymore. I used to think lumia was great to have offline maps and navigation (it helped a lot!) but now android have here maps too, i dont see much point of buying WP device anymore.
when people say WP10 universal apps would solve the app gap issue, tbh i doubt it. look at Windows 8 store, it's the same thing with WP8 store. there are too few apps there. The reason people dont build for WP is because developers prioritize android and iphone (due to market share), and not because they dont want to build two different apps for windows 8 and WP8. it never was the main issue. I think most people who use windows 10 would still be laptop and desktop users, and not tablet users, therefore it wont make much difference because most developers would only develop for windows standard desktop apps (because people spend their time there) and not the modern universal apps.
i do hope im wrong because i actually want windows platform to succeed but tbh i dont see much future in WP. not even in windows 10, it still feels very similar to windows 8 imo (yes, i tried the technical preview)
