When you have one wire in one hand out of a braid of 90 and wonder where to plug it, you don't want to have to get up, flip through the manual, find the right wire reference (try remembering "AX45Y", "45YT5Y" etc all day long), read the corresponding graph and go back to your station. The alternative with Glass is, read out loud the reference you have in your hand and it tells you where to plug it right where you are, hands-free.
