I'm not sure if OB Forums is the best place for this question but I'll give it a go knowing many of you own one of these.
I've had mine for 5 years and they've been nothing short of brilliant in that time. However I feel technology is getting ahead of them now, as I dabble with 4K video (and even rendering 4K back down to 1080p) the WDTV either can't read it or it's unwatchable. The thing is I was about to buy another WDTV soon but now I'm thinking I will sell what I have and move on to the next thing.
Problem is, what is the "next thing"?
I don't want AIO computers, just a simple media player to replace what the WDTV has done all these years.
I assume you don't have a smart TV. I would be inclined to post your requirements for a device, as something like a Roku might suit you, or any device which talks to a Plex Media Server.
