Been using various iOS 5 betas (and now the GM) for awhile now. One of my favorite features (besides proper notifications, of course) is Safari Reader. Basically, it strips away all the cruft from a webpage and simply displays the content you want to read. It works similar to things like Readability (www.readability.com/).
It's especially nice, since it presents the content in an eBook like format and you can dynamically resize the text.
Something I find interesting though -- I haven't really been using the "Reading List" feature. Basically, it's a way to temporarily bookmark articles and websites you want to read late. As far as I can tell, it doesn't do offline access though (so, I'll still be sticking to Instapaper for my offline needs).

Safari Reader -- One of my favorite features in iOS 5
i started using the reader on my mac and when i noticed it on the iPad i started using it there also. i agree its great how it removes all the adds and just gives you the basic text of the page.
