Kindle DX comes with the larger screen is a definite plus. I use the larger type size on my Kindle 2 (older eyes), and at this type size I get far more text per page on the DX. This makes the whole reading experience more book-like and should be a boon to people who buy large-print books. The cover is also sharper and crisper than my Kindle 2 in a side-by-side comparability: the text is darker, and the contrast is often improve, making for better perceptibility overall.

On a side note, the larger screen also makes it possible to read poetry on the kindle reader, even at large type sizes. On earlier Kindles, the smaller screen cut off lines, so that you would lose the sense of when the poet ended the line. On the DX, you can see the whole line exactly as the poet meant it, with the cut-off in the right spot.

The PDF reader works as advertised, and is extremely handy. PDF documents appear on the DX exactly as they do on a computer screen. Moreover, you can pull and drop your documents direct to the device using the USB line (or use the for-a-fee email if you absolutely must.) The only downside: at least for the documents that I’ve used so far, I cannot adjust the type size as I can with native Kindle documents.

The screen rotation also works as advertised: it operates as a mild zoom on both graphics and text and offsets slightly the downside of not being able to adjust the typesize on PDF documents. One nice designing touch: the four-way direction joystick introduced on the Kindle 2 is rotation-sensitive, and give relocation as expectable relative to the display movement.

And many of the style space is devoted to the screen, while the whiteness plastic boundary around the screen seems to get shrunk, both in comprehensive and compared to the proportion of display to plastic on the Kindle 2. I suchlike this (but see below about the keyboard).
I like the increase in storage space, and don’t mind the lack of an external storage card. I can see some people having trouble with this, but only those folks who either must regularly carry around PDF documents totalling more than 3.5 GB of space or must have nearly 3500 books regularly at their fingertips. I fall in neither category.

With Kindle DX has long battery lifetime, you can read on a single charge for up to 7 days with wireless on. Turn wireless off and read for up to 2 weeks. Battery life will vary based on wireless utilization, much as shopping the Kindle Outlet and downloading collection. In low-coverage areas or in EDGE/GPRS-only coverage, kindle dx wireless usage will consume battery power more quickly.
