Expose is one of the coolest utilities on Mac OS X and I’ve been looking for a Windows equivalent that works just as well. A good graphical task switcher is useful on any Windows XP computer but especially good on the Sony U since the screen is so small. TopDesk is exactly what I was looking for. Completely configurable, it is lightning fast, smoothly animated and it makes working with multiple windows on the desktop fun and easy. It has three optional buttons to make using on a Tablet PC easier. Sweet. $10.
