Perhaps we can begin a new "sticky" post but I am always interested in what other IT pros are using in their "tech" lives...and how it changes from time to time. I've recently become a convert of using "whatever works" over being "all in" with Microsoft products and ecosystem...so, guess I'll start:
Home:
Dell XPS 8700 with 16 GB RAM, 1TB SSD, Windows 10 Pro, GeForce GTX 645 (my primary file/media sever)
Plex Media Server
Seagate Business Storage Windows Server 4-Bay NAS 8TB
WD MyCloud NAS (2 units)
Surface Pro 4 (basically, my main PC)
Amazon Echo (Alexa)
Cloud
OneDrive
Amazon Cloud Drive
Google Play Music
Amazon Music
Groove Music
Mobile
Samsung Note 5
LG Watch Urbane w/Android Wear
Media Center
XBOX One
Plex App
I am currently in transition with my cloud services and music providers. I've been in the Groove ecosystem ever since Zune but since the app on Android is weak (no music scrubbing / fast forwarding), I've decided to try Gogle Play Music. Though ever sense getting an Amazon Echo, I like the convenience of using it for Amazon Music. Their PRIME catalog is way behind Google, Groove and Apple Music but I love to tell Alexa to play something. And Amazon Music has decent apps for the phone and desktop (it has lyrics on a lot of songs). If I can live with less "free music", I may just use Amazon and just buy albums not in Prime that I want . But, I don't know, sometimes paying for Google Music (which includes YouTube RED) is worth taking ads out of YouTube videos... 
With Cloud storage, OneDrive seems too quirky for me. I actually mapped my main file server libraries to OneDrive but I always have a handful of files with sync errors but no way to fix them. Amazon Cloud Drive doesn't work quite like OneDrive but it doesn't have to if I need an occasional file. I may always use OneDrive for personal, Office documents. And do I dare say the Mobile version of Excel saves to OneDrive way better than full Excel? I'd always end up with corruption or version problems.
