Just a word of warning; the 4K Steaming Sticks appear to have incredibly poor WiFi performance. This hasn't been an issue with the 2 I use in my home environment, but in a school setting they are receiving around 20% the connection speed of an Apple TV sitting in the same vicinity. The issue may be the design; tiny little stick crammed between a wall and a tv which has RF shielding inside it, but regardless of *why* it's happening, the result is that AirPlay is almost unusable, even though many other services function OK. For example, looking at my network console I can see that one of my two Roku 4K sticks is connecting around 25Mbps Rx and only 6Mbps Tx rate. AppleTV (3rd Gen) connected to that same TV connects around 120Mbps Rx and 150 Tx rate. A 4K Apple TV in a nearby but essentially identical installation (same room configuration, same distance from WAP, same radio power, even same brand of TV) connects at 325/400. So this is not a small difference; the Roku is connecting at a catastrophically lower rate than the Apple equipment in identical configurations. (Well, as identical as they can be considering the design of the Roku).
