I was really interested after this comment if only because Calibre really is an iTunes for ebooks:
1. It has updates ALL THE TIME
2. It has a billion features and I only need one (moving books to/from the device)
Unfortunately, after looking over the feature list and realizing that it's for Linux, I realized that this is more of a replacement for Books on OS X -- a local ebook reader.
A good, basic ebook reader for Windows is FBReader. The Windows version hasn't been updated in years (development seems to have shifted mostly to Android) but it still works just fine.
