It’s similar to Apple Spotlight, limited to links (it’s not a desktop search like Spotlight or Google Desktop), but it’s useful to launch your programs without using mouse.
Just type alt+space and write what you want to launch, you’ll be prompted with more options similar to your search.

Launchy is a free windows and linux utility designed to help you forget about your start menu, the icons on your desktop, and even your file manager.

Woopra is a statistic program very complete, with a beautiful and catchy interface. It needs online registration and activation (it’s still in beta and you’ll be activated after some time) and you need to download the client to install on your computer.
Woopra has more features, and the most important thing it’s there are organized and ready to read and understand; I think it’s better of Google Analytics, because it’s more direct and immediate. But if you want custom statistics, use Google Analytics.
You can view all features, some are really innovative, like the live tracking (I adore it) and the chat with visitors (wow!!).
