I have the GPSMAP 60Cx and I'm very happy with it. I took it skiing recently and it performed well. I could push the buttons with gloves on. I also use the same unit for in-car navigation, on my push-bike as a speedo, and for hiking and geocaching. It's good to have one unit that is so versatile.

The -x models are a big improvement over the older ones. I didn't bother with the altimeter and compass partly because I have those functions in my EDC watch, and if in the wild I'd be carrying at least one real compass anyway. I wouldn't want to be solely dependant on the GPS in case it got a flat battery or something.

Using 2.5A/h rechargeable AA batteries they do indeed last about 18 hours.
