Add another accessory to the small-but-slowly-growing Nike+iPod ecosystem. The Nike Amp+ watch is a futuristic-looking piece of tech that may or may not jibe with your aesthetic. Besides telling the time using a series of LEDs, the Amp+ includes ever-so-subtle raised buttons that let you control your iPod Nano (unfortunately, it doesn't display any running stats like time, distance, or calories burned--you'll still get those fed to you through your earphones). You can also hit a button on the left just as you hit that brutal hill to fire up your motivational song. The watch comes in four colors--black and gray, black and red, blue, or green--and a polyurethane strap can be hacked to fit your wrist size. Runners can now get in on the action for $79.
