Why heft and schlep your golf clubs and bag around by hand when you can have an electric cart do it for you? The BagBoy Navigator 2 ($2,000) can be operated via remote control, using the handle controls, or manually like an old-fashioned golf cart. A built in navigation system keeps the cart in line, and helps it maintain speed even when ascending or descending hilly or rough terrain. Propelled by two 140-watt motors, the Navigator is powered by a 34 amp battery that will last for a full day. With this cart and a little practice, you'll own the fairway just like Mr. Dangerfield.
Whether you're biking, boating, hiking, or doing some other activity, the Cy-Fi Sports Speaker ($180-$200) lets you listen to tunes without forcing you to wear earbuds. Available in both iPod and Bluetooth varieties, the Cy-Fi creates a wireless connection between the lightweight speaker and the content source, letting you change tracks and control volume without ever taking your device out of your pocket.
