Honest question: is it any good? I deal with A LOT of pdf files on a daily basis (theoretical physics) and I've always wanted a big-screen, e-ink reader (plus free wireless access to Wikipedia, if I remember correctly).

I felt it was good when it first came out. After using the Kindle Paperwhite with touchscreen, it was hard for me to go back to the DX.

One of the most annoying parts about the DX was the PDF zoom. If the margins on your PDF are too big, the zoom doesn't function to remove the margins and zoom in towards the center. If I remember correctly, it zooms towards the left, leaving right half of the page cut off and still fat margins. It was so bad with some textbooks and papers that I had to go manually cut out the margins of the PDFs using an editor.

You can always read PDFs in Landscape mode, but that tended to be clunky on anything with 2 columns. In landscape mode, 1 page will become 2-3 "pages" that need to be traversed back and forth to read the separate columns. The Kindle caches the next page of the PDF but not the previous, so using the back button on PDFs could take a little bit depending on how big the PDF file was.

As long as your pdfs translate well to grayscale it should be fine.

The new kindle web browser is quite nice (I believe it uses webkit) but isn't something you'll want to use for anything that you want to get done quickly.

I haven't tried this new DX but I love eink screens and feel that they are much easier to read than laptop/ipad or other birgh screens.

I think it's the same ol' DX, just back in stock.

Probably a bad idea if you want to take notes or quickly skim through content. Pretty good though if you want to read from cover to cover without making to much fuzz with notes etc.

Not interested in taking notes -- and yes, I read those files thoroughly (and, sometimes, painfully...) from the beginning to the end.

I don't know anything about the Kindle DX, but I do think K2pdfopt is an essential piece of software for reading PDFs on an e-reader (I have a Kobo Glo). It allows you to reflow the text, and convert two column text into a single column. Even image based (scanned) PDFs.

I have one and a nasty case of buyers remorse:

1. PDF reading is the pits

2. The device is just big/heavy enough for me to never want it with me. Won't fit in any pocket, bulks up my slim briefcase, is hard to handle with one hand.

I'm waiting a while to allow myself to get a paperwhite.

All that said, you can have mine for $99 if you need one!

Not really. Too slow, low dpi compared with current Kindles, no wifi and it's 3G only.

A colleague bought one expecting to read papers on it & as far as I know has barely used it. That said, it is better than the other Kindles if you want to read a lot of A4 PDFs & can cope with the slow (oh so slow) page turn.

Until the retina iPad, I preferred my old original Kindle DX for reading black and white PDFs.

I now prefer the retina iPad for PDFs I need to rapidly navigate, but still appreciate the DX for reading research.

This might even be the one with full free 3G browsing, full stop. I believe I remember that being available on the K3 Keyboard and the DX.
