One of the things I like about some newspaper apps on the iPhone or iPod like the Guardian or New York Times is the ability to read articles offline. This is not just handy when you don't have a connection at all. It's far quicker to download in one batch, especially on a wifi connection, than have to download each page on a slower 3G connection. My only workaround is to use the Guardian RSS feeds, which include full versions of the articles, but it's not exactly elegant.

Any suggestions?
