Title pretty much says it,
I would go out and buy a nexus player for my parents but it does not have any ethernet
My parents have a NAS storage box and i cant imagine wifi or 10/100 ethernet doing any good"
all the ones i have seen with GB Ethernet seem to run android 4.4, i would prefer the latest 5.# with leanback launcher
Thanks
UPDATE
Hey all, in the end i went out and got a Nexus player, and im happy with it, runs kodi perfectly, just need to find a micro USB ethernet adapter, i got this over the shield and forgetv as they are not available in australia and it would have cost me a minimum of $350AUD to import one, and then get an adapter for the power, until maybe androidTV picks up the nexus player is damn fine for $130AUD, thanks for all the helpful comments guys!
Most people add on a USB hub and then plug in a USB -> Ethernet adapter.
Alternatively, the shield TV has what you're looking for.
Side note: those Android boxes running 4.4 or whatever are just using regular Android and have an HDMI out on them. They are not true Android TV devices, more akin to hooking a cheap Android tablet up to your TV. General rule of thumb: avoid them.
