On a demo today Leanne Lowe announced that later this year Sage will move to using Skytap for their demo images. Essentially this is a cloud based virtual machine. No more Technet. This looks to be a much better solution since you can demo from anywhere you have a web browser and no more managing images on laptops. (Yes, you will likely need an Internet connection - and no I don't know how they manage offline use).
