Google’s foray into the ebook business, which was supposed to happen earlier this year, was officially unveiled today with the launch of Google eBookstore.

I’ve already downloaded the iPhone app and a couple of free books so I could take it for a spin. I found the experience comparable to reading on my iPhone using Stanza and by that I mean enjoyable and easy. You can choose your preferred font, adjust font size, line spacing and choose day or night reading mode.

There are more than 3 million books available and enough free ones to last you the rest of your life. In perusing the list I noticed most bestsellers priced at $9.99 and some as low as $4.99. The books are readable using iPhone and Android apps, web-based reader software for your laptop or desktop and on most eReader devices…except the Kindle.

The books are kept “in the cloud” allowing you to access them from anywhere an Internet connection is available. You can bookmark a spot while reading on your laptop and pick up at the same point on your smartphone or eReader device. And you can buy your books through Google or any of several independent partners. No matter where you buy your eBooks, they all appear on your bookshelf which, by the way, has unlimited storage.

Do you read eBooks? And if so, is the Google eBookstore something you would try?
