I'm curious if people actually use the IR in place of their TV remote as in the promo. For me personally, I think the friction of having to fire up an app first would preclude me from ever using it in earnest.
I used that feature once. Long day on a construction site. Last job was to hook up a PC to a Smart-TV. No remote to be seen. Costumer no longer on site. Jelly 2 to the rescue :-) Felt Swiss Army knifey.
I have the jelly star and I do use this feature. It's useful if the remote is missing and you need to adjust the volume or something.
I aslo used it when I was working away from home and was trying to plug my laptop into a TV HDMI port. I had no remote and couldn't switch the input manually but was able to do it with the phone.
