I'm acquiring a Mac laptop in the summer, and as such will be running Bibleworks and Logos via Parallels. I've been using BW since the early days of v.4, and Logos for about two years for library purposes. Since I'll be running on a Mac, I'll also be able, should I wish, to make use of Accordance.
Now, I've never used Accordance, but it appears to be more like Logos than BW, in the sense that it's more of an electronic library with search functions. Since Accordance has some things available that neither BW or Logos have (I'm thinking here primarily of the NWS Inscriptions database and its companion index), I may well end up running all three. I appreciate that Logos and BW can interlink with each other to some extent, but Accordance, being a Mac program, can't.
It's frustrating that we should have to choose or switch between programs, to some extent, based on the database offerings, but I suppose from another perspective, it helps marketing to say "We have database x and no one else does!"
