My dream GPS weighs 2 ounces and has a roll-out 14'x14" screen. My main issues with a GPS is weight and the horrible tiny view screen and poor viewing in bright daylight. I have never been able to "see" a landscape well with zoom-in, zoom-out. I am really comfortable with USGS 7.5 minute maps and I do not even take a compass. Finding north is just not that hard to do without a compass. And I love to lay out all my maps and see both the exact tiny place I am while also seeing the entire trip route.
