I'm pissed off. I wanted to buy this technical book, and so I clicked on the links to buy it (small publisher) and whatnot... paid for it... then I got e-mail in my box that it was ready for download. I paid $20 for a PDF. Grrr... Looking back on the site, it did state this, but in a roundabout way. I mean, it's a book I need, and I have read through the PDF, and the writing is good, the info was what I needed, so I can't say it was a ripoff... but still: I hate PDF manuals. I can print 240 pages, I guess, but what a pain.
