This article mentions the Good client as a one of these new solutions when in fact it has been around for several years.  For those that have used the Good client they should know from their users feedback that it is not so “Good” a solution.  Also, ATT has their Toggle solution which is also available now that tries to accomplish the same task of separating corporate and personal data.  The challenge that these solutions have is in providing a good user experience so that at the end of the day the customer can’t tell a difference between the native email app and the one in the secure container.  Thus far, in the products that I have reviewed there has not been a solution that has provided a good user experience.
