Smart Devices?
Perhaps we should call them stupidly designed gadgets bought by people with more money than sense.
Though it's hard to get things WITHOUT internet built in. The solution is DON'T connect them to your WiFi or ethernet.
Why has "Marketing" and "Media" decided that something connected to Internet makes it "smart". It would be nice if I could use the ethernet on my Sony TV to say, browse and play stuff on the server, in practice the Android TV GUI is a joke, the T&C you must agree to Google/Sony Slurp just to tune aerial is an insult (Is it even legal?), the inability to record on a USB HDD unless it's dedicated, wiped and encrypted, the voice control, monitoring of what the HDMI BD/DVD player does etc means that it's just a crippled version of TV that's not "Smart". No way am I connecting ANY setbox or TV today to the Internet/my LAN.
