just switched over to it this morning, and thus far i am VERY pleased with it. it's fairly light and simple, seems to have a fairly simple and easy saving system that would be transferrable to other machines (and easy to backup).
AND it's the first client i've successfully used to import my 300+ megs of outlook mail, with the correct folders and mail, etc.
very pleased, i'm just doing some research on wether the win files are compatible with the linux ver files, if so i've got myself a new mail client
