The Kindle DX battery life was atrociously low people were reporting sub 50 hours/2000 page turns....

not the 3g voyage, unfortunately. with mostly default settings (including auto-brightness on the screen), mine barely lasts a plane-ride across the country.
my partner's dx, on the other hand, had no problems whatsoever.

eInk achieves excellent battery life by being completely unpowered when the screen isn't changing. When you press the "next page" button, you're basically booting the whole device, having it render the next page, then shutting it off again. If you're using any sort of backlight (as "auto-brightness" suggests) then you won't get that benefit and I'm not surprised your battery life is more like that of a traditional tablet. The DX doesn't have a backlight so wouldn't have that problem. If you turn your backlight off then you should see similar results.

turn off backlight, turn off 3g, turn off touch, and turn off force feedback (i am not sure if turning off touch will actually render it to act like a dx).
The Kindle battery last for 1-2 months (book reading, it only consumes energy if you turn the page -> e-ink display!).
The iPad battery last for 1-7 days, depening what you do with it and how bright you set the IPS display.
Many own both an iPad as well as a Kindle - both have their advantages.
(edit: I meant WiFi-only Kindle)
