When it comes to picking out a great gift, there are three rules that I stick to. First, buy something that you would like for yourself. Second, buy something that the recipient is unlikely to buy for themselves. And third, buy something that you know the person will use. I refuse to spend my hard-earned paycheck on something I think might end up gathering dust in a drawer.

Since almost everyone I know owns a smartphone, listens to music, and likes to travel in style, this means I'm usually gifting some sort of gadget. This year, my list includes metallic suitcases that are easy to track, bangles that charge your iPhone, DJ-worthy devices, and, for my nieces, Play-Doh sets with a magical, connected component.
