Garmin took a page out of Apple’s book with the Oregon 400t, the first handheld GPS unit with a touchscreen and an icon-based interface. The result is the most user-friendly and intuitive GPS unit we’ve tested. The touchscreen keyboard makes entering info a cinch—something testers really appreciated when temperatures dropped. The 400t also comes loaded with a complete set of U.S. topo maps, and we love the 3-D color maps. It’s also waterproof and housed in a burly rubber casing, and you can share data with other users wirelessly. 1GB, expandable; GPS;
