I loaded a .gpx file with 2200+ caches, it only took 30 seconds to import. Not bad considering the amount of data.
The individual Geocache screen has a good amount of info.
VantagePoint does a great job with Cache files, but it appears that the Triton will not be able to show the description or logs. This is a real bummer. It appears that paperless caching will not be possible with the Triton (are you listening Magellan?).
