OK sure, I missed one of the ways you could use it. I guess you could use them for distributing data along with "storage and movie backup" I mentioned before. However, at $20 a pop, it's still way too expensive, which I also mentioned. I'd rather burn 5 DVD+Rs for less than $2. Does 10x, or $18 premium justifies the convenience of carrying one disk instead of 5? Probably not, at least not for the average user. If on the other hand you need to transport 437GB you'd be better off to putting all this stuf on one or two harddrives you already have and bringing them to your buddy. Wasting $360 for blueray media just so that you can transport the data once to a different location and then throw them out is stupid. Not to mention blueray writers cost $1K and both parties would need to have them. Well, if you and your buddy can afford $1K burners, sure you can afford to throw out $360 in media cost.
