While riding I've been using User:jackchallen's Tapwave Zodiac http://en.wikipedia.org/wiki/Tapwave_Zodiac instead of my Palm TX as the transflective display is far easier to see in daylight. Unfortunately the hardbuttons on the Tapwave are easier to press accidentally, exiting cotoGPS or turning the device off. I've lost a few tracks by the buttons being press just from movement in my backpack, which is very annoying. Putting the Tapwave in a hard case stops it happening.

From playing with CetusGPS it seems that app. wont respond to button presses while in tracking mode, only to a specific screen tap, which is exactly the right behaviour for a being used as a datalogger.

The only thing I need now is a program that will display maps, trekbuddy (running under IBM J9 java VM) would be ideal but it causes PalmOS to reset :/
