This brief introduction to Windows 8 covered the key items that enable you to navigate and work with it on the client and the server, but the best teacher is your own hands-on experience, so just install it and start playing. As mentioned earlier in the chapter, see http://www.savilltech.com/videos/win8nav/win8nav.wmv for a demonstration of the material covered in this chapter regarding interacting with Windows.
Windows 8 will bring Windows to a wide range of new devices and use scenarios, supporting both touch as a first-class interface method and much smaller form factor devices because of advancements in technology and the ARM version of Windows. The key point is that a device running Windows 8 will offer a no-compromise experience, with the ability to run all the Windows applications and enable all the manageability that has become standard with Windows. Devices running Windows RT will be able to run all the Metro-style applications and feature the same interface experience as the other Windows 8 editions. Like anything new, once people get past the initial shock of the changes and begin to use it, I think the experience will be positive.
