By copy & paste I assume you mean the clipboard API?
The biggest PITA in my experience is that the DOM works differently so lots of JS libraries don't work (nodeName is lower case, you can't use document.createElement)

Copy (and probably paste) is only plain text. Copying formatted text from Firefox into Microsoft Word gives different results for XHTML vs. HTML. Drag-and-drop has similar issues.

Didn't HTML5 fix document.createElement so that it does the right thing? If the document is an HTML or XHTML document then the namespace is the XHTML namespace.

Yup, looks like it does the right thing now!
