If you're the outdoorsy, adventurous type, this will no doubt be of interest to you. Garmin's just outed two new touchscreen, handheld GPS devices -- the Oregon 450t and 450. These mid-range devices both boast 3-inch displays, weigh in at in 6.8 ounces, and supposedly get around 16 hours of battery life on their two AA batteries. They also have 850MB of internal storage, microSD card slots, and can store up to 2,000 waypoints, 200 routes, 5,000 caches and a track log of 10,000 points and 200 saved tracks -- good news for avid hikers, no doubt. The main difference between the two units here is that the 450t comes preloaded with topographic maps of the entire United States, with coverage of major trails, urban and rural roads, interstates, highways, coastlines, rivers and lakes, national, state and local parks, forests and wilderness areas. Both units are available to order now on Garmin's site, and the Oregon 450 retails for $399.99, while the 450t will cost you $499.99.
