Just got into Kodi myself after having problems with another box that cannot be updated for H.265.
I went for a Tronsmart X5 Windows 10 box (don't like android) it's about the same size as the android boxes.
Came with a full licensed Windows 10 Home edition, so I can install anything I am used to using.
I thought I'd give Kodi a try, but I'm not a fan of all the nice graphics and menues so I usually use Total Commander to browse to me NAS to play stuff.
I do like the IPTV stuff in kodi and a few other things like Shoutcast radio.
It wont index my music collection, keeps stopping after the first 3 albums for some reason and I had a real pain of a time adding TV shows to the library because of the filenames (only played with this to see what the fuss was about).
Had to use kodi 16.0 beta to get it to play H.265 files, whereas potplayer and windows media player played them straight away from the windows desktop without installing any codecs. Also 1080p TV shows seem to look better when NOT played in kodi for some reason, probably settings.
getting the sound sorted in kodi was also a pain as I needed the passthrough option for my amp to use DTS, but this made the sound cut out for a few seconds at the beginning of each show. But windows was setup correctly for 7.1 surround and all the speakers worked as they should.
Gotta say I'm very impressed with this little windows box though. I like that I can update the codecs as new ones are used, dunno if you can do that on Android, but it was the reason I stopped using my old mede8tr box as it was Realtec based and the codecs on the chip.
