All the time. It’s how I launch nearly everything.
On my laptop, I find the 4-finger-pinch gesture to bring it up far more convenient than digging through Finder windows or putting apps in the Dock.
On my desktop Mac, I mapped the otherwise-unused F19 key to bring it up. I realize that F4 is permenantly mapped to Launchpad, except that I have my Mac configured to treat F-keys as F-keys, so I would need to type Fn-F4, which is less convenient than just tapping the key at the top-right of the keyboard.
