A feature which I have not seen done properly on a PC is Dashboard, this allows you to press a Key (built into the Apple keyboard) and it makes the background transparent – showing your Widgets.
Why is this a good thing? You can see at a glance the Date / Time which can also include any other clocks such as timezone for another country. The uStream Widget allows me to quickly check which ones are live and the Map of the UK there is a Web clip.
What is a Webclip? in Safari you can clip any part of the web page which is then shown as a widget on the Dash Board, in this case a radar of the UK which is always updated when you go into the Dashboard.
