We gadget nerds have to endure unspeakable atrocities in order to slake that early adoption jones: first-run gear shipped DOA, buggy pre-release software, and months of waiting after a product leaks only to be greeted by a jacked-up price premium at launch. So we feel your pain, original Kindle owners, after Amazon announced a major firmware update that brings native PDF support to the 6-inch Kindle 2 and DX readers with the promise of a staggering 85% increase in battery life to all Kindle 2 devices -- if you haven't already received it OTA, the 2.3 software update is now available for download and installation via USB tethering. At least owners of "some earlier versions of Kindle" (quote from the press release) will receive native PDF support whenever the 1st generation firmware update (currently at version 1.2) is released. It's worth noting that Amazon's PDF reader lacks a zoom function which makes many PDFs entirely unreadable on the device. Good thing Amazon's store is chock full of easily zoomable books in a proprietary format then, huh?
