If you've not gotten a chance to see Allison Watson's Keynote address at Microsoft Worldwide Partner Conference (WPC) conference or on the web, you can check it out at http://www.microsoft.com/digitalwpc/ in the keynotes tab. If you skip ahead to 1:51 you can watch our very own Jameel Khalfan demo the Replaceable PC.
Using Windows Vista Enterprise, Bitlocker, Profile Virtualization, and Application Virtualization, we were able to take a laptop with all of Allison's settings, backgrounds, files, and applications and drop it off the stage. Then we logged into a brand new laptop with her credentials and all of her data, settings, and applications instantly came down. This is a great solution that our customers and partners can implement today to help reduce costs and downtime for end users. Even if the PC is lost or stolen, Bitlocker will keep the data protected. Plus, it is a pretty impressive demo.
