For anyone interested in the latest Windows operating system from Microsoft here is a nice early chance to get a look at it way before the launch with the developers preview. Alongside this is an excellent video that makes a decent attempt to show what Windows 8 is all about, though anyone with a windows powered phone will already have an idea of what it is going to be like.
According to the new Windows Dev Center;
The Windows Developer Preview is a pre-beta version of Windows 8 for developers. These downloads include pre-release software that may change without notice. The software is provided as is, and you bear the risk of using it. It may not be stable, operate correctly or work the way the final version of the software will. It should not be used in a production environment. The features and functionality in the pre-release software may not appear in the final version. Some product features and functionality may require advanced or additional hardware, or installation of other software.
