I've owned every model of the Kindle (minus the comically large DX)

Funny, I would buy something like the DX ("like", as in price and battery life) for reading PDFs of the textbooks, magazines, journal articles, and so on, that are my ordinary reading material, if the screen weren't so comically small.

I've had a DX for around four years, and absolutely love it for reading PDF's (mostly of academic papers). It's light, the screen is clear, and it works well with all of the PDF's I've thrown at it. (This includes PDF's that are scans of 40 year old papers.) My one complaint is that it doesn't have a lighted screen for night time reading.

(I also have a Kindle Paperwhite 2 that I use for books. I've tried PDF's on on the paperwhite, and it doesn't work nearly as well as on the DX.)
