A couple of weeks ago, Apple’s in-app purchase rules change resulted in a number of companies with iOS book reader applications to remove links to their online bookstores from within their apps. Along with this change, there was some speculation that this might encourage the introduction of HTML5 based web applications to sidestep Apple’s rules.

Last week Amazon fired back with its own web-based Kindle Cloud Reader. This iPad optimized web app in a hands-on review by Jacqui Cheng at Ars Technica on the whole got pretty good marks for a 1.0 release. And, of course, it integrates the Kindle Store into the app. By all means, read the review and check it out for yourself at read.amazon.com. While not a complete replacement for the native iOS and Android apps yet, in our increasingly networked world, it won’t be too long before we’ll no longer notice the difference. And the speed at which Amazon introduced the cloud reader suggests that this project has been underway for some time and will likely see future improvements.
