Out of curiosity, what are you missing? I was fully invested in google services. Drive, Maps, Photos, Music, Wallet, Hangouts, you name it. But windows phone had an alternative for everything except Google Wallet (which I can still use online) and some Chromecast features, like casting from 3rd party services: Netflix/Hulu. I can still cast personal media and from Youtube which is all that I find important.
I guess I could see having this problem if you aren't actually willing to switch to Microsoft services, but I feel like that comes along with the territory of using these phones.
