For those who are interested in a TRUE MSN client for Palm OS, QuickIM (www.quickim.com) is definitely worth trying.

I've tried basically all popular IM clients out there, such as VeriChat, Mundu 4.0, Chatopus, etc... I finally settled on QuickIM because not only it has great interface, but also a unique feature that I've been craving for years - sign in as MSN mobile.

This feature allows QuickIM to directly connect to MSN servers and identify itself as mobile messenger. My friends now are able to know I sign in from a mobile device, instead of from desktop. This is really important for me because my friends used to get upset when I don't reply them on time. Now with QuickIM, not only can I get a cool mobile icon, but my friends wont complain if I dont reply when i am on the move.
