Have a Mac and love to use Quicksilver / Spotlight as your application launcher or document finder, but are forced to work in the windows world for food? Or if you secretly want a Mac. Then Launchy might be the application for you.
I don't know what I would do without Spotlight. Having to actually find documents / applications through all my directories is a major drag. But I've been trialling Launchy for a week now (requires some hacking to get it working in Win2k) and it looks like the Windows solution that I'm looking for.
Hit ALT + SPACE and a Quicksilver like window pops up like so:
Type in the first couple of characters of the app or document you're after and it finds it for you. It's ... unbelievable!
