alt Hacker NewsThey're missing support for newer codecs and current WiFi standards, can't decode Dolby Vision FEL, and, unless something had changed recently, they don't keep up on security updates (even if they are pushing out other updates).
I suspect the last point would be true even if they launched new hardware, though.
Also the current hardware has lots of overheating problems that hugely affect performance (you have to re-paste the heat sink to the CPU after only 2 years), and thier Bluetooth antenna is so awful it makes Bluetooth controllers for gaming completely unusable due to lag from lost/dropped packets (and the remote constantly disconnect and reconnect randomly).
