Windows 8 seems to me to be a mix of Apple, tablet , Ubuntu and then Windows. A best of. Visually it can be quite stunning. I don’t like the raging bright colour combos of the metro screen but I can see it might have wide appeal and in a classroom on a whiteboard the metro interface would create a lot of interest and could be landscaped to target specific learning areas, needs and specifics. Windows 8 is colourful and has some good transition effects, really interesting visuals and so could provide quite a dynamic interface in a classroom. It can then be just Windows and you can do whatever you normally do on Windows. In Windows 8 the corners are significant. Bottom left is a hotspot for the metro interface. Top right gets you to the side toolbar. Bottom right is minimise and top left I really am not sure! Run the cursor along hte top of the screen and you see a hand. Pull it down and you will minimise that desktop and can create another. I have survived on ALT F4. Without it I’d be lost. It is how I shut screens down when there is no obvious way to shut them down. It is how I shut down the computer from the desktop. The power button is in SETTINGS!!. Press the Windows key and C and the toolbar will come up at the side of the screen. Click on settings and there’s the power button. In the metro screen you can click on your picture. it gives you the option to log out. When you do that you will see the power button bottom left. The lack of ease with the shutdown could create security problems. If you use your picture on metro then you can easily find it. Looking for the power button in settings is not obvious and so provides a security issue on shared computers. It also means some people might just turn their computer off and not give data enough time to save. It seems odd not to have an obvious power button, but still , the world is odd at the moment.
