I really like the Read it Later (iTunes link) app for iPhone.

I come across a lot of articles that I want to save for later reading, but do not want to bookmark permanently.  Read it Later is sort of an in between space that lets you save web pages for reading later either on your computer or on your iPhone/iPod Touch.

The fact that Read it Later syncs between computer and iPhone is the big plus here: I can find and save articles on my laptop over morning coffee and read them - yes later, at lunch or on the go, on my iPhone.  Of course I can also do the reverse and save articles to be read from the iPhone for reading on a PC.

There is a little more too this than just downloading the app.  My one warning is that the process for installing the bookmarklet on Safari for iPhone is a little difficult but you will want to do it.  Fortunately detailed instructions are provided.  On my Macbook, I also installed the Read it Later bookmarklets on Opera browser with no problem.  Once the app is installed on iPhone, and the browser bookmarklets installed, you are ready to rock and roll.
