We took the Motocaddy M5 GPS DHC out for a test drive at a local course. This thing is loaded with features, including a 3.5" GPS touchscreen that has 40,000 courses loaded and gives distances to the front, middle and back of greens, as well as hazards. The rechargeable lithium battery has a crazy amount of juice (36 holes, easily) and the cart has variable speeds so you don't have to chase it down the fairway. Check it out.
