I downloaded the Kindle app and like reading books on my iPhone. I like it better than actual books, especially since I can change text size and color -- plus background color (go sepia!). But with Sony's popular reader and the introduction of the Nook, I'm really getting worried. I want to get a Kindle because I have about 5 books I have already bought from Amazon, but the Nook does look quite intriguing. Then you have the Sony reader, which I have actually seen two inches in front of me and which is a little bit cheaper. Amazon has its own eBook format. The Nook I'm pretty sure has its own. Sony? Duh, it's Sony. So we have probably have three popular readers with big backers (Sony, Amazon, B&N) and three proprietary formats. This sounds like as big of a win for consumers as adding a third format to HD DVD vs. Blu-ray would've been. I understand the need for DRM, but why does everything with DRM require closed formats? How long will we wait for these chuckleheads to battle this out? Oh yeah, what's Apple going to do? Is Apple going to back one of those three formats or come up with its own through the iTunes store?
