I've recently gone the POD route. I was well aware of the negative aspects of this type of publishing prior to plunking down my money. I'm with iUniverse, and I've yet to experience some of the claims made in the article. For instance:
One Author copy: I took advantage of a monthly promotion and received 35 copies, with no shipping fee.
You pay extra even if you provide your own cover art: Not true.
The printed books are poor quality: The paper should be white instead of the way-off white they use, but the cover, binding and layout are very good.
It can take a long time to get copies shipped to consumers: Based on reports from people who've purchased the book from the website, it takes one week for their copy to arrive. That's the good news. The bad news, is the almost $8.00 shipping fee. That's way too high. And the book itself is priced at $16.95 for a large format paperback. That too is high. I'd prefer a less expensive, standard sized paperback option. The trade paperback size significantly reduces the number of printed pages. It makes my 85,000 word manuscript look almost like a short story.

Anyway, that's my 2 cents.
