I like that it gives me more control over my emails, rather than having to rely solely upon Gmail or Yahoo! for all of them. It is relatively easy to use; however, there are some things that could be simplified (such as adding multiple accounts). If you're looking for an alternative service from your current provider, this may do what you need at a reasonable price point. We have been able to move away from Google Apps by creating our own hosted server - which has allowed us full ownership/control with no restrictions other than those we place ourselves.
