What's the purpose of having separate checking and savings accounts?
Additionally, it used to be the case that savings accounts would have a noticeably higher interest than checking accounts (if the checking account paid any at all).  So you would attempt to maximize your cash working for you by putting as much as you could into the savings account and then only transferring out what you needed to cover bills, etc into the checking account.
