A real good book. As a new Palm developer the database sections were indispensible. The conduit descriptions are good too. There are only a couple things I can say I wish it had.
1) Complete API reference with examples (maybe this could be a PalmProgramming in a Nutshell book like UNIX in a Nutshell). I found things like sysBatteryInfo missing.
2) Examples hotsync2/cdk2 as well as version 3.
It's definitely a must have.
