Its all good considering the updates are not very often, plus I just want to try one of this boxes
If you are going down this road, I'd look at the Beelink R89, also branded under Ubox. The devs at Freaktab at least are developing ROMs for this one. But the price is in the same price point as Nexus Player, although it has more ports. These were just released over the last month or two, but the specs are impressive RK3288 with the latest Mali T764 GPU.
