lchiu7: I guess my main issues with the Firestick are its remote which is proprietary so you need to get use one around together with a universal Harmony I also use. And given the size of the Firestick remote, it's easily lost :-(
I've found that because the AFTV Stick is plugged into an HDMI port my TV's remote works it just fine. TV is an old (2011 model) Sony KDL-46EX720.
That's a very nice TV. I had a EX710 and I thought it had one of the best pictures I had seen in many years.
