Tempted to upgrade my nans old TV with a cheap WebOS or Android TV television from NCP group.
According to one comment on Geekzone from 2020
They've been around for a while; they basically just localize cheap stuff out of China.
$500 for a 50" 4K TV seems decent. The most she would do on it is watch live TV and YouTube. Maybe Netflix if I got it for cheap. Could try save some dosh by buying a factory second version for $400, but it only comes with a 12-month warranty.
Considering second-hand as well, but there's not much on Trade Me at the moment. She lives in the Bay of Plenty area. Alternative option is to finish setting up this 4K Chromecast I have and attach it to her old 40" TV. Bigger TV would be nice though.
