I for one don't own a blu-ray anymore and really don't want to - they feel to me like LaserDiscs or BetaMax at this point! :)
Plus, to fathom a three-year-old-destroyer-of-property handling your blu-ray disc collection, I shudder! They are great frisbees, and coasters, and etc.
If I even still owned blu-rays I might consider ripping them and then converting to this just to avoid the above mentioned pain.
