[metaphor]

The point of the disillusionment exercise was to carefully select parameters that favored narrowrail's perceived "advantage" in an improbable but still realistic way.

In other words, assuming a proverbial couch potato got a sweet deal on a new Roku 3 and pays up the wazoo for electricity, it would take a solid 4 years of usage in the prescribed manner before breaking even on a relatively small investment, rendering any perceived power savings "advantage" over an existing 20W system null...let alone other considerations like product MTBF, lifecycle, the next trending 6-second attention getter, interoperability, etc.
