You are right. But, I have an extensive library of PDF files that I'd like to read. I expect many people do too. Most are technical documents with equations, graphs and other images. I would love to have an e-ink based reader that will render such documents correctly.
But, Amazon are probably more interested in selling their content, so I understand the lack of PDF support.
I have an older Kindle DX which can do technical PDFs. Aside from the cost (nowadays triple the smaller Kindle), it's still not entirely satisfactory for three reasons:
- It's cumbersome to do anything other than reading sequentially.
- The screen is still not big enough for letter/A4 pages - it does perform decent scaling, but you know how scrunched many technical papers are. Can go landscape and read half a page, which is a pain in two column layouts ...
- It's a tad heavy, almost like a hardcover textbook that needs to be held in both hands.
