Query: Really now.

Frustrated with the dearth of good Korean language learning workbooks, I sent the following email to the publishers....ram files? Really? Why bother making the files availiable if they are essentially useless? If they were mp3 and I could learn via my player on the go, then I would buy your book. I'm sure the irony is that you didn't make mp3s files out of fear of piracy which might affect sales. Gj.While were at it, why punish your customers by making them download each of 50+ files individually?
