Blackboard vs. Moodle

If you are looking at using Blackboard or Moodle as your LMS, consider several items I have experienced using Blackboard.  First, students don't like BB because of the multiple clicks to get to places in the course.  Second, BB doesn't play nicely with iPads,especially as an instructor.  Third, file management in BB is far too cumbersome and time consuming in uploading multiple files.  Finally, cost!  BB is expensive whereas Moodle is free with minimal hosting cost.  Does anyone have experience with D2L (Desire to Learn)?  Would love to hear from you about your experience.
