U.S. Internet giant Google's online bookstore, Google Editions, looks like a potential game changer for the electronic book industry, a reviewer wrote.

Google's outlet will resist the temptation of tying access to Google Editions books to a specific reading device, such as a Kindle, PC World reported Friday. Instead, the launch of 500,000 titles in the first half of 2010 will be available through a variety of hand held and desktop devices.

"To me this sounds like Google wants to turn the e-book, or more accurately the e-reader, into a Web App," wrote reviewer Ian Paul.

Others digital outlets, such as Buy Ebook and eBooks.com, have content available that is "unchained" from a specific gadget, however, "whenever Google gets involved with any new business, the immediate assumption is that the company will be able to reshape the market," Paul wrote.
