Professional-grade content available for free is definitely a good thing.
Pro Monthly subscriptions are now available

Pro Free digital game conversions available for download
Con Not fully cross-platform anymore
Although earlier versions of Mac OS X are supported (v10.1.5 through v10.6), more recent versions of Mac OS X (those lacking Rosetta support) are not. And there is no official support for Linux (but users have reported success running the program in Wine or Virtualbox).
