I'm not sure, but your desktop might be running IE7 instead of IE8 - the newer IE8 is better generally, but the toolbars compressed better in the older version.
You want to right-click on the toolbars and play with checking and unchecking the settings to show what you want. You might be able to combine things from different toolbars by dragging them all onto one, then uncheck the empty toolbar so it disappears. Just play around to see what it lets you do.
If you look at the "Customize" you can find an icon for "Full Screen" that you can drag into the toolbar. If you click "Full Screen", all the toolbars will disappear leaving the whole screen for web pages to display, until you bring the mouse cursor up to the very top. This is handy for the little netbook screen, in particular.
Personally, I like FireFox browser better for many reasons, including that a user can get all the different buttons and search boxes into one single toolbar leaving more screen space.
