One of the exhibitors at this event was Belkin, demonstrating their new range of Pure AV cables and power supplies (yes, you will be able to get a UPS for your home media set up...). Part of their range was a conditioned power supply for home AV equipment - with a diagnostic display on the front.
All very useful, and nicely encased in brushed aluminium. However there was one sad thing we learnt. Apparently focus groups saw the PSU as having one killer feature. It wasn't the fact that it would protect your expensive home cinema equipment from power surges, lightning strikes and power outages.
No.
It was the fact that you could choose to illuminate the display with a range of different LED colour effects.
I guess they might be right after all.
Never overestimate the general public.
