Be sure to keep the INGO classifieds in mind in a couple years when you replace that unit.
I have put more than one "outdated" electronic device to use on my network. These old units are great for dedicated streaming devices. Police scanner apps, radio/tv streams, etc. They are great for chromecasting to big screens and sending to speaker systems via bluetooth.
Often "old" android units have very nice cameras that will WIFI security type video over your home network and beyond also.
This. I usually use Swappa when looking for used equipment but you can scour ebay and other places as well. Lightly used flagship devices from the last couple years will be comparable in price to the current budget like devices and be better equipped.
