Ha ha, but you're forgetting that there are a lot of people who use selfies as part of their business on social media to drive people to their sites, remind them of upcoming concerts, and to show themselves doing positive social good.
Flip it around and it would also be a great daytime fill light when shooting video with your cellphone.
Other uses, for politicians to shoot themselves with constituents, autograph hounds with their prey, and for those good parents (unlike the rest of us) who want nice photos of themselves with their kids.
So we may think it's idiotic, but there are a lot of people who will use this gizmo as part of their work and for that it looks like a pretty good piece of kit.
