I've had one but have seldom used it. If find the OS is difficult to navigate and seems more interested in selling me stuff than it is in helping accomplish stuff. Last night I was trying to figure out how to get it to work HEOS on my Denon X4300H receiver, my new toy. I got it to work with Amazon Prime Music, but couldn't get Spotify to work. It would only play on the tablet and not on the receiver. I'm having a hard time figuring out how to close apps. I went so far as to power off the tablet, at least I hope I did, and Amazon Music just kept on playing on the receiver. WTF? If you know how to close apps, please let me know. Any tips and tricks you know about using it would be appreciated. My version is the 7".
