Amazon has created a Web app version of its Kindle reading software for Safari for the iPad, Mac OS X, and Windows, and Chrome for desktops. The app uses HTML5 to mimic the natively written Kindle apps, and does a quite decent job. Amazon leverages HTML5 local storage support to download Kindle titles to the browser, too. This is seen as a workaround by Amazon to bypass Apple’s 30-percent cut of media purchase fees in iOS apps. follow link
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work.
