vApps: To use or not to use?

Back in September, Cody Bunch at ProfessionalVMware.com, had posted an article regarding an e-mail he had received from one of his readers about vApps.  Besides the fact that it was a good read, I have found that vApps are extremely nice for use when deploying multi-tiered applications and organization.  Per VMware, a vApp can be defined as:

A vApp, uses the OVF standard to hold information about your multi-tier application. That is, it will hold information about service levels, policies, security, as well as the components of the application (read: VM or VMs). Containing all of this information will allow the owner of the vApp to move between internal and external clouds

What are your thoughts on vApps and how they can be used?  Sound off in the comments!
