My main use is for geotagging photos and tracking trips. I prefer this one because you can chnage the configuration directly on the device without the need to connect it to a PC and run an application to chnage the configuration. This is useful when tracking trips that you want to change the data logging mode from time (say every 5 seconds) to logging on a set distance.

Maplin used to sell this for £129 which was too steep for me. The normal price is £79.99
but reduce until 24th Dec 2009 to £49.99.
