I couldn't agree more. I'm using ownCloud with InstandUpload to handle photo backup, and ownCloud itself for the DropBox equivalency. With Cal-DAV and Card-Dav enabled, owncloud let me disconnect from Google Contacts/Calendar. Owncloud support for rainloop means that I have GREAT webmail (which I never use) and more importantly, an IMAP server I run on top of this. It's becoming a lot easier to disconnect, with the sole exception of the Google Play store.

More importantly bitnami makes it a one-click install for all of the above, minus the IMAP server.
