They probably got a great bulk deal on them

I spent the day at a conference in Charlotte today. Instead of giving us the usual printed handouts they gave everybody a 2 GB flash drive with the handouts on the drive. Not that they needed that big a drive.
Most of the rest of the conference was fairly low budget, so either somebody gave the sponsors a bunch of flash drives or the price has gone WAY down. Printing and collating a bunch of handouts isn't exactly free, but it doesn't seem like it would be very expensive.
I'm not complaining at all. I am certainly more likely to find a use for the drive than for a pile of papers.
