Perhaps not for you, but for me it was a surprise that find that I could copy and paste complex portions of a web page (like the table from this page) in Safari into a note in Mail.app.
From there, the complex note will sync nicely onto the iPhone -- where you can then float it above the yellow Notes background to see the entire content.
