I haven't been on the forums for a while, so TBH the update was a bit of a surprise. I did find myself grumbling slightly when the new interface booted up and things had changed, but that's just human nature I guess. I'm in my 50s and I've seen so many interface changes on Windows, Linux, Raspbmc etc, it's just progress. Down to the nitty-gritty though, does it still play my vids & music? Yes. Any performance issues? None I could see. Sadly the spectrum visualisation is now well and truly gone, which has made my 13 yr old daughter decide not to update because she likes it.
I'd like to take slight issue with the comment way back about if you're not familier with the CLI, why are you using kodi. My wife uses it to watch the US programs I download for her and she's a right Luddite. She still hasn't got her head round the idea that the videos she is watching are not actually "on" the Pi, but are on a network share hosted on a linux box in the garage- see, her eyes have glazed over already.
Looks ok to me. All working nicely here on a Pi2.
