And potential reliability issues too. The storage infrastructure of something like dropbox will (or at least should) be massively redundant to reduce to near-zero the risk of people losing data due to hardware fault.

With something like OwnCloud you need to provide your own live redundancy and backups if your data is important enough to need them.

Having said that I'm looking at using OwnCloud for myself, and might suggest the group I work for use it too if my experiments with it show it to match out needs. But do be aware of what else services like dropbox provide that you need to manage and support yourself when replacing them with an in-house service.
