I just purchased Deaths Head from ebooks.com in Adobe DE format for my Sony PRS-505. It's unreadable at the two smallest fonts and way too large at the largest. I've looked for options to convert ebooks to other formats, but it seems DE files can't be converted. Ebooks.com is disinclined to give me the book in another format (wtf?). Am I basically screwed here?
On a side note, I will never purhcase an Adobe DE file again. I would really prefer some positive outcome to this, but if I can't view the file properly on my device and I can't get a refund I'll simply cancel the credit card charge

. And companies wonder why the average user hates DRM so much.
