got it and like it so far. I like how the screen is still visible in bright sun, and doesnt require backlighting to make it visible. This will be a huge plus for biking, as I tried using my cell phone and it sucked. Leaving the screen on drained it in no time with the GPS. I was able to get about 10-14 hrs before it stopped. (just hanging out on my window). I think I do want topo maps though, so I will be inserting a memory card inside.
