Just point your mobile browser to http://aka.ms/wpdemo and you can access an interactive HTML5 page. The demo allows you to experience the look and feel of the Windows Phone 7.5 interface, as well as walks you through some common tasks such as checking email and sending a text message.
Overall, the page is very responsive and gives a nice introduction to Windows Phone 7.5 for a first time user. It remains to be seen if this tool will actual convert someone to Windows Phone, but Microsoft has definitely come up with a very simple and creative way to get a taste of its software into the hands of its competitor’s customers.
