It's right there on the home page:

"Sublime Text is available for Mac, Windows and Linux. One license is all you need to use Sublime Text on every computer you own, no matter what operating system it uses.

Sublime Text uses a custom UI toolkit, optimized for speed and beauty, while taking advantage of native functionality on each platform."

Are we talking about some other sublime?

Shows me for not actually double-checking, I was pretty convinced. Is that a recent addition or is there another editor I'm thinking of?

No, it isn't. From the website:

Wat?
