Comment on LaunchBar

To use an ancient, worn out cliché comment:

"This should be packaged in the default OS X installation."

Or something along those lines… It's just that good. I don't feel anything more than that is necessary to say. Just give it a try and you're bound for a completely new experience using computers.

I'm just curious, is there anything similar in the Windows world, of the same competence as LaunchBar?
