What people don't focus on is really the top line experience from Virtualization, and we think that can be just as powerful. We think if you go to a Virtualized type of approach you can be more responsive to the needs of the business. You can roll out applications quicker. You can bring out new services to support your customers. Now, there are some technology reasons behind this. If you build out a uniform structure where virtual machines are the basic building block of the data Center, you can start to think about how you can scale the resources more effectively as the demands on your business grow. I need more CPUs -- order up some virtual machines. I need more SAN storage for a particular application -- let's grow its dimensions or take it down, as the business demands need. Another aspect of this is how applications are written. So these applications can be written from the perspective now of a virtual machine. What does that do? It completely abstracts it from the physical infrastructure. So as that application needs to move forward in time, it can move to a new virtual machine environment, where the CPUs, the disks, the underlying infrastructure is completely different. I hope you can see how that can make you more responsive to the business.
