Glad that you've had a good experience with Android although I think you'd have to agree that a core i5, 8gb ram and 126 ssd isn't exactly a description of a Chromebook. I'd expect WIN10 to move smartly on that setup based on my experience with my wife's system which is the same except for a 500mb HD.
My data collection concern is based on what's happened in the Google environment regardless of app permissions. The OS underlies it all and essentially bypasses next level up permissions although I'm sure the less sloppy among us are escaping some notice.
As someone observed during an earlier time, "Even the paranoid have real enemies."
