A big question college students should be asking is, "What IT and electronics knowledge will be most in demand five or six years from now?" In these fast moving niches, an answer is almost impossible to come by. But what if you were one of the people who supplied raw components to the electronics industry? Wouldn't you have a better handle than most on what kind of devices and components are becoming more popular among prototypers and engineers? And wouldn't watching those trends possibly give you at least a little insight into what the future might hold? Randy Restle, Director of Applications Engineering at component supplier Digi-Key Corporation, carefully tracks orders and tries to determine what's hot and what's not. His reason for doing so is to figure out what Digi-Key should stock in coming months and years. But his insights can also be used to decide what you might want to study or -- if you're already working in the field -- what products you or your company should consider developing. Digi-Key also has an online video library where they feature new products and give ideas of what you can do with them. Even if you're not an engineer or electronics hobbyist, it's fun to see what's available but may not have hit the mass market quite yet.
