It makes no sense to push to the server before they're done, why do you do this? Are you afraid your hard drive is going to go kaput while you're on the plane,

It makes no sense to push to the server before they're done, why do you do this? Are you afraid your hard drive is going to go kaput while you're on the plane, or you're not taking your computer with you? That's the only reason I can think of to do this... git is not like svn, where commit and push are the same thing; on git, a push is the same as publishing for others to see, the commit is what's important and it doesn't require a net connection.
