Buzzword: Alpha Geek

What it means. Alpha, the first letter in the Greek alphabet, has spawned a lot of power-hungry personality types, including alpha males and alpha moms. The latest members of the Order of Top Dogs, alpha geeks, are perhaps not as tough as those other alphas though they do typically have a strong interest in cutting-edge technology.

Alpha geek term first gained traction in office culture as a way to describe the person with the most technological know-how. (You know, the coworker you seek out when you can't figure out how to download pirated files through your company's ironclad firewall.)

Alpha geeks strut their stuff outside the corporate world, too. For example, your Apple-crazed friend who happily waited in line overnight to buy the new iPhone 3G is an alpha geek, as is your cousin who's been LinkedIn since early 2004 and sends out annoying invites to join LinkedIn to you and the rest of your family.

Why the buzz? Electronics aficionados are the most likely to be alpha geeks, but home and garden enthusiasts can be AGs, too. Consider cooking technology. An alpha geek will adore induction cooktops, which continue to impress our engineers and whose prices appliances are dropping.

Alpha geeks are surely joining the steam revolution, a technology that has found its way into many appliances, including dishwashers, washing machines, and even ranges. Steam modes are supposed to improve performance, although our engineers haven't found steam a noticeable improvement.

Outside the home, alpha geeks will probably know the pros and cons of zero-turn-radius mowers, or "ZTRs," as they no doubt call gear like the Cub Cadet shown above. They're also likely enamored of robotic lawn mowers, which are about as high tech as any outdoor power equipment can be. Note that one of the two models we tested was not acceptable.—Daniel DiClerico
