lol. The app is now relabelled as "Amazon Kindle", which means it appears top of the application list
Magazine selection isn't very enticing, and PC Magazine shows as "not yet available". Less than 200 newspapers (compared to PressDisplay's 1,500), but it's easy to buy a single issue rather than a subscription (i.e., like buying it at the newstand), especially with the one-click pay.
Newspaper format is the same EPUB-like format as used by most other newspaper providers (like PressDisplay), but the colour is nice, as is the ability to navigate with fingerswipes instead of the stylus.
