The internal quad-helix antenna is excellent. Position accuracy is superb, screen resolution is vastly improved, and the extras such as tidal and celestial info are a really nice touch. The optimal fishing/hunting time predictor seems like overkill but I'll bet there are users who swear by it. The routing and tracking functions are well thought out and much improved since the 12XL was released. WAAS is sort of a mixed bag. I find that that whenever I lock onto WAAS signals, the estimated accuracy gets a few feet worse. It's never reads more than 20-25 feet off total but it's still the opposite of what I'd expect. Regardless of what the estimated error reading is, the accuracy always seems much better than it lets on. I've been using it a lot for geocaching lately and it invariably puts me within 5-6 feet of the caches.
The MetroGuide CD is quite nicely designed for a Windows product (I'm a Mac fan!) It contains substantial improvements over Delormes Street Atlas 4 Mac which was the last CD based mapping product I owned. It's fast and accurate (I understand that they just updated all their maps) and the integration with the GPSMAP is excellent. You can easily transfer all waypoints, routes, tracks, or maps back and forth between the GPS and your PC (or VirtualPC for Mac fans). You can also connect your GPS to the serial port and dynamically track your whereabouts on your laptop screen but I find this arrangement a bit cumbersome. There are just too many wires and batteries to deal with. For me having an easily readable, high-resolution, zoomable map on the GPS is the only way to go.
The only complaint I expected to make was with regard to the limited 8 MB map storage space. It turns out that 8 MB will hold pretty much the entire San Diego, CA and San Francisco, CA Bay Area. If I were driving across the country and wanted to investigate every nook and cranny I might be concerned. Otherwise it's perfectly fine for now.
Great product, great price. Happy navigating!
