I think the biggest win for these devices are uses that aren't even commonplace yet. I've been working out separate functional networks for home automation, my workshop, and our inhome entertainment. Working with a very tight budget, this sort of device will let me remove most of the administrative/configuration functionality that's not needed for daily use on those networks and secure it in the absence of better industry-standard options. A lightweight, super secure version of Linux and my safe will make this fun =D Granted, that's not an everyman use for the device, but hey - we're called early adopters for a reason!
