As previously mentioned I recently bought myself a Palm TX PDA. One of the important factors for me when choosing this PDA was the ability to HotSync to my Linux desktop and/or laptop. Using the gpilotd daemon and the GNOME Pilot Applet this is pretty easy.
I have a wireless access point at home and therefore thought it would be nice to HotSync the Palm to my desktop over WiFi, rather than plug in a cable. The process of HotSyncing over wireless is pleasantly simple. My desktop has a fixed IP address (which is dished out by a DHCP server, but it always gets this address because the DHCP server knows the desktop MAC address). The Palm can be configured to obtain an IP address via DHCP or it can be given a static IP. I read the MAC address of the label on the back of my Palm and fed it to my DHCP server so that it would dish out a static IP to the PDA when it appears on the wireless LAN.
