Yup, it's alright but has a few niggles, usually the community version, have not really had experience with the enterprise but heard it is the same roughly.
It sometimes suffers from the occasional hiccup with the client software and local syncing. I.e. misreporting the amount of space available and refusing to sync based on 0GB being available.
On occasion from the client it won't sync all files properly or will crawl the same files on occasion. Discovered it uses a file comparison system which sometimes has issues with volume shadow copy.
When you use AD integration, it doesn't really like LDAP signing as assigned by group policy (depends on your group policy and security settings within your domain).
It can be great when you need to share lots of the same files between people and have them work remotely. Most of our experience is through the clients (Mac, Windows) through remote usage. Works better than DirectAccess most of the time when sharing a large number of constantly updating files between a group of people.
It is easy to use when things work, but if you encounter problems where it simply refuses to upload files to the server or re-upload it can be frustrating. On the odd occasion it does seem to ignore permissions and give access denied on certain user created directories if you use the encryption component.
Depends on what you want to use it for really. We went back to Sharepoint after using it because it didn't really fit our needs, again we had previously used Sharepoint and all our internal staff knew how to use that.
