The only downside to the Sentry LX is the fact that it occupies two whole drive bays which can put a damper on your case-chi if you use more than one DVD-ROM or mount hard disks in noise dampening cages in your 5.25” bays.
So, the logical progression was to reduce the size down to a single bay, but how do you maintain the same functionality as the LX without the use of buttons? - Simple conductive membranes which switch on contact provides a cheap and effective touch screen solution.
