The always thoughtful Erica Sadun of TUAW on why Amazon is mum on the new iOS subscription rules:

Amazon’s Kindle for the Web has been in beta since September 2010, offering a potential web-based alternative to a native iOS app.

Wow. I was unaware of this. Makes a ton of sense. I think that web apps can be solid, but it’s still not the same experience. The official WordPress app is not very good. And while there is a plugin that creates a usable mobile version of the WordPress control panel, it’s still not as good as a native app would be.
