I use it every day, but I can’t imagine paying monthly for it. It might sound silly for the SaaS folks, but I grew up buying desktop software, and it feels insane to pay for it as a subscription.

(Incidentally, I also use Transmit FTP, Screenflow, and Deckset almost daily as well. They're not SaaS. I happily pay for new version upgrades if I feel I need the new improvements).
