I only managed to export Contacts from Palm Desktop and it required extensive bash scripts processing csv fields. The Palm Desktop & Evolution fields just do not map.

Also, Evolution syncing with GPE is full of bugs. I lost nearly 90% of my contacts data after the first opensync, including, but not limited to, residential addresses and all phone numbers. Probably my fault since I used non-usual Evolution fields for storing data as a result of my custom importer.

Gpe-calendar contains also some bugs which may or may not be showstoppers for you. Syncing repeating events which span DST shifts is nearly impossible. I've been woken up at 3:00 a.m. a lot of times due to shifts accumulating after each sync. Awful. Forget about any kind of "complex" repeating event rules like the PalmOS had -- GPE and Evolution each treat those in their own incompatible ways.

They were right when they told me that N810 was not a PIM device. Fortunately, seqretary and some recent PIM developments may change that. But they're still not even feature complete.
