Wireless charging is perhaps one of the best examples of true convenience. The simple act of setting your phone down meant its battery would begin refilling. No need to hunt for the end of a cable, no more time spent clumsily aligning plugs, and no more hassle with loose cords. When the Nexus 4 was announced, its stylish charging orb was supposed to spearhead a movement of wireless bliss. While the orb certainly had its advantages, it was a bit late to launch and carried a premium price.
