Bicycles and ereaders, cats, it's summer time! If you plan to read for fun or research in the sun while bike touring, and you don't want to carry extra paper weight in your panniers, consider an ereader. I've simultaneously tested the Sony PRS-T1, the Barnes and Noble Nook Simple Touch, and the Amazon Kindle Touch. This post focuses on which ereaders sync ebook annotations across devices as well as the ebook file in the cloud. It also explains how different vendors deal with your public library ebook annotations. It took me a while to figure this out. It is not super clear on the manufacturers' product specs. Read on and look at the whiteboard diagram. Remember: It is technology. By definition, it has to change.
