We have the ATV4 in our living room and absolutely love it. We have the ATV3 in our bedroom since we don't have a cable box in there and it works quite well. I have the opportunity to pick up a gently used ATV4 for $100. We are on the brink of cutting the cable cord completely, so not being limited to the apps on our ATV3 would be plus. Given the opportunity, would you upgrade the ATV3 to the ATV4 even if you already have one in another room?
