One big difference you will notice in Internet Explorer 7 is the tabs along the top.

Look along the top of your screen and click where the red arrow indicates.  Now type a new website address in the bar along the top and press the Enter key on your keyboard.  After the page has loaded you can skip easily between the two websites by clicking on the tabs.  You can continue adding more tabs the same way.

Did you know you can have more than one home page by clicking the right edge of the home button  and selecting Add or Change Home Page...

If you add pages to your homepage tabs you can have a few home pages like this

ready to go when you open up Internet Explorer.
