In brief, the press releases says that *native* PDF support is coming to the Kindle, together with a better power management through an upcoming over-the-air (OTA) firmware update. Here’s a snippet of the actual press release:
SEATTLE–(BUSINESS WIRE)–Nov. 24, 2009– Amazon.com, Inc. (NASDAQ: AMZN) today announced two new enhancements to the latest generation Kindle—85 percent more battery life and a native PDF reader. Kindle now has battery life of up to seven days even with wireless turned on, a significant improvement from the previous battery life of four days. Battery life with wireless turned off remains at the previous level of up to two weeks. Battery power management for portable wireless devices is a complex technical area, and the battery life improvement announced today is the result of a six month firmware improvement and testing program.
Current users who need to read PDF-formatted documents has to send those files to Amazon. After converting, Amazon will then send the converted document back to the users through Whispernet. I tried this service once and I was not very happy with the document sent back to me – to much formatting errors. But once native PDF support is rolled out, users should be able to simply copy over those documents to the Kindle and it should be displayed “as-is”.
