Much like the Kindle for iPhone app, Kindle for PC syncs your Amazon e-book downloads and shows them on your computer for convenient reading either when you're away from your svelte e-book reader or if you chose not to buy it in the first place. A Mac version, Amazon says, is "coming soon".
Though not necessarily revolutionary, the Kindle for PC app does the job. Among other benefits, it syncs your last read page with Whispersync, syncs Kindle notes, and promises to use Windows 7's touch technology, allowing readers to pinch-zoom, and, in future releases, turn pages with finger swipes.
Amazon is reportedly working on the ability to create notes and highlights on your PC and a search function. What you can't do is view blogs, newspapers or magazines.
