I have been waiting for Logos for Mac, the Bible research application suite, for over a year. I take that back: I have been waiting for Logos for the Mac for over five years, when I first switched to Mac after a brief and unfortunate experience in the Windows world.
Before we go any further I must stop to address the fear which has already gripped many Mac users. Let me say this clearly: this is no hastily slapped together Mac "port" of a Windows application. In fact 15 seconds into the introductory video, they proudly announce: "What we've done for the Mac is rebuild it from the ground up."
You can tell.
Logos for Mac looks and feels like a native Mac application. How native? If you can copy a passage from Logos to Microsoft Word for Mac, it automatically creates a footnote in APA, BibTex, Chicago, Harvard, MLA, Refer-BiblX, RIS, SBL, or Turabian format (whichever you choose in the preferences). As someone who has no love for footnoting, this may be my favorite feature of any piece of software ever.
