While earlier versions of KDE had a Windows-like interface withe a pretty standard start menu and taskbar/panel approach, KDE 4.x has a widget-based interface that lets you easily customize your desktop and panel with widgets that let you interact with your computer, desktop, and web apps. Kubuntu 9.10 also replaces the Konqueror web browser with Arora, a new light weight browser based on Webkit.
