Yeh same thoughts as Brave Little. My fam are good with slight changes and will adopt if its easy. It ok if i do it in small stages and i explain what and why. I have the same long term plan with consoles/phones so moving has to be a discussion with give and take.
The biggest note is when i have visitors, if its too awkward they will baulk and try and connect the device the old way.
I don't like Kodi either, tried it decades ago, even with advances and skins its still too overwhelming looking vrs a screensavers and cards approach. I kinda like having my apps separate somewhat like android.
