Create document from Gmail

A new lab feature in Gmail lets us create a Google document from within Gmail. At first I thought it wasn't very impressive, but after trying it with an HTML email, I was quite impressed by the new feature.

One way I could find it useful is when I want to have a PDF version of my email. I could simply just create a document out of the email and download it from Google Docs as a PDF file. I could have printed the email from Gmail but that's not how I want my PDF file looks like. So, I think this new feature is pretty useful. =)
