Gigabit Ethernet gets us above 100 megabit. For those of us that use the Roku for a PleX client streaming movies to it. 100mb is a bit to close for comfort. NASA Thermonuclear Art for example is 200GB for a 17Min video. So streaming "LEGIT" 4K videos will not always work at 100mbps. Also common place is ripping blu-rays so that they can be streamed to PleX. As I said before a few of the 4K demos I tested were 75-80 mbps and those were just demos. Grande com is offering 400mbps internet around these parts for like 45$ per month. I'm just saying that a device released in the year 2016 as a 4K device and Gigabit network adapters for PC selling for $8, just seems like a mistake to not include the "Standard" Ethernet connection used today. They actually came into use in 1999.
I'm just saying Roku says "next generation of streaming technology" on the box, yet has 100mbps Ethernet (and USB 2.0). I cant be the only one annoyed by this.
So my advice to any one thinking about a Roku 4, as an owner of one and also Roku 3, 1, and Stick, Get the Nvidia SHIELD. It has all of these features and even supports 24p playback.
