BBP:I saw something recently about Sharkpoint that also included a GPS function along with the Palm Pilot. Looked pretty cool but I'm not sure if the dollars equal the practical part. Sounds like a neat gadget though.
I myself use SharkPoint for a while. I like the easy to use interface, the GPS/GIS option, photo album and option to sync to my palm (ppc is also possible). And the 24/7 support is coolio too. See for yourself http://www.dreamdives.org
