"Front" is meant to be absolute, not relative, I believe. Most people would not be confused when talking of the "front" of an oven, or a car, or a mobile phone, or a tablet. Meanwhile, "left" and "right" are also absolute in that they refer to your left and right in your habitual posture with respect to the device. Few people operate an oven with their back to it, but you operate a car while facing out of its front.
Think of pretty much every home device: your TV or stereo, when you face it, has its left speaker on your left, right speaker on your right, controls in the front -- ie the side facing you -- and wires in the back -- ie the side pointing the same way as your front.
Perhaps some (geeks, I expect) find it confusing, but most "normal" people wouldn't :)
