I picked up two blu ray drives for my main machine and my HTPC.
Immediately I encountered the need to update firmware had to use rubbish software like cyberlink to play the disc. For licencing reasons there are very few pieces of software that play blu ray discs. VLC can play blu ray streams but it don't expect it to play the disc like if you had put in a DVD. If you aren't using Windows you can pretty much forget about playing the disc back without workarounds.
My advice to you would avoid blu ray completely. Consider just getting your media from another source. I think Netflix
now offer high def streaming services.
If you are absolutely insistent on blu ray discs I'd seriously consider just picking up a standalone player or a PS3.
