This update also sees big enhancements to Quickedit, Action Launcher's powerful icon editing system which offers suggestions for icon replacements based on icon packs on your device. (androidcentral.com)
The other big enhancement (mentioned earlier) is the Kindle DX's native PDF reader, enabling Amazon to target the professional market, where financial documents, reports, marketing flyers, and even PowerPoint presentations are commonly published as PDFs. (macworld.com)
I guess I'll hold on to my PW 2 in the hope that the next big enhancement will be adding TTS to at least one of their devices. (thekindlechronicles.com)
