Yeah. Like you said earlier, the price would be insane if they used a higher storage USB. But the mp3s and vid, if I'm not mistaken, only used, like, 800 MB (.8 GB), so I don't know why they couldn't have made them more high quality. Maybe they wanted to leave availible storage space? But for $75 USD, I could get an new 32 GB USB.
It doesn't really make sense. Maybe it has something to do with the mass production of the files?
