Not so new at all

But, while the new iSync might lack the ability to sync files, it does (finally) include some conflict resolving features. If entries on your various devices conflict, you are presented with a small window describing the conflict and allowing you to choose how you want to resolve it (i.e. which device takes precedence). You can also check a box to have all conflicts with the same devices involved be resolved in the same manner.
This is not new at all to me, i am quite sure, this feature has already been arround for quite some time.
However i agree 100% with him on his feature request about syncing files. I'd like to see this implemented by using .mac to ONLY store file-metadata and not actual files (as in Backup) and based on that metadata sync files from different macs.
In OS 9 we already had a similar feature. There was a Controlpanel (forgot the name) which let you sync files across harddisks or shares. It worked quite well and i do miss it a lot. Especially since i have various desktops and a AluBook which i'd really like to automatically keep in sync with the some files/folders from the desktops.
