Nowadays a brand new high end +2000€ Samsung TV comes with ads (!) in the menu and the apps feel like they'd be running on a potato. With that kind of Smart TVs, the hardware won't be the issue since it'll be the software that will be obsole way before the hardware. Smart TV is not a promise, its a thread.
Also nowadays it would be useful to have some sort of debug port, for example a serial port to connect and have a CLI to do diagnostic, upload a new firmware, etc. They have these interfaces in the TVs but most of the time are either disabled or protected so the end user cannot use them.
