I have X8-H as my current Android TV box, mostly for Kodi. My biggest gripe, is the lack of OS upgrades (it is stuck in 4.4, and no updates in sight), while the software (Kodi and plugins) move forward requiring new OS versions. In my search for a replacement, I came across the U1 and Z83-4. I never even considered Windows 10 vs the Android OS. Windows has a far longer OS lifespan than Android with more backwards compatibility. So, what should I consider going from Android to Windows 10 for a TV box? What unexpected issues await me? Why isn't a Windows box more popular than so many Android TV boxes?
