Your TV's USB port is a nice feature, but it's not a major selling point. Most people purchase a TV for watching content, but it's capable of more.
Modern TVs come with various ports, including HDMI, USB, and Ethernet. The usefulness of these ports depends on individual circumstances. For instance, the Ethernet port may not be useful if the TV is far from the modem.
The USB port can be useful, but its utility is limited. For example, it can be used to power a Roku Streaming Stick, eliminating the need for an external power source. However, even this has limitations.
Most people buy a TV to watch things, but you might not realize it's capable of a lot more than that.
In conclusion, while the USB port is a nice feature, it's not a key factor in purchasing a TV.
Author's summary: TV's USB port is overrated and has limited use.
