The Audio Bulb: wireless lightbulb speakers

Wow. There truly is a market for everything. The AudioBulb is a lightbulb with a built in speaker that plays music through any wirelessly transmitted device. These bad boys even come with a remote control. But this is what I am wondering: what good is it having a speaker that plugs into a light socket with a burnt out bulb? Until the infinite lightbulb is pioneered I don’t see much success on the horizon for the AudioBulb.
