Since I'm running my first review of a PDA-based GPS receiver today, I thought I would briefly cover the advantages and disadvantages of these units, compared to traditional handheld GPS receivers:
- Ability to display raster maps.
- Can perform more functions (word processor, datebook, MP3 player, Bluetooth, etc.).
- Larger screen.
- More fragile than most handheld GPS receivers, which are "ruggedized." This is primarily due to the touch screen.
- Shorter battery life than most handheld GPS receivers.
The bottom line is that these can be a good solution for automotive navigation or paperless geocaching, but they aren't a good choice for backcountry navigation.
