Pros Paperless caching is the best thing since sliced bread.
The "Rock & Roller" interface is fairly intuitive for most situations.
The Wherigo player takes geocaching to a whole new level.
Wireless transfer is very useful and quick.
Cons GPS accuracy is uneven.
Text and data entry with the "Rock & Roller" is tedious at best, downright frustrating at worst.
As of update 2.6 GPS drift is a problem, sometimes as much as 200'.
Digital compass only works when unit is held level.
Pros Great graphics, user interface
Cons unstabe, inaccurate, crashes, battery life
Summary I bought this in place of the Garmin famous 60Csx model since it offered a newer product and it really looked good. However a couple of weeks I returned back to IRE to get the simpler but rock solid 60Csx.
As for 400t it has an extremely short battery life and unstable system (even with the updated OS). It takes long to power. It also hangs and crashes so it is not a safe companion for remote outdoor use. I spend time in the woods and mountain areas. I need something I can feel safe with - 400t is not it.

Pros Good color screen, rugged.
Cons Clunky user interface, inaccurate.
Summary This GPS took me backwards 500' before correcting the direction. The map swings unpredictably around the tracking arrow, making navigation difficult. I've registered .5 mile distance errors in as little as 3 miles. Garmin's solution was for me to reset the user data, which I did. Now the maps I've loaded (and reloaded) don't show any detail. This product could have been fantastic, but is more suitable for a paperweight than a GPS. I do not recommend it.
Pros Easy to use. A lot of feathers. It was very helpful on a road trip to find motels and restaurants.
Cons The backlight defaults to dim when it is turned off. LIke all garmins, the trip computer starts the time when the Receiver is turned on, rather than to have a button to push when you are ready to go. Programing the destination could be easier.
Summary I have used it for hiking and on two 1000 mile road trips. Expensive, but worth it, for me.
