Telly Terminate
The Telly Terminate is a small keyring gadget to turn TVs off. It appears to have sold well during the recent sports event.
Pro: It turns TVs off.
Contra: It's flimsy and much too wide for use on the keyring. The long, narrow shape of most USB sticks would have been much better. As it is, the Telly Terminate acts like an anchor, and fetching the keys from a tight jeans pocket tends to pull the chain out of the anchor. I replaced the chain with a carabiner.
Update: It broke after about a month.
