Excellent point.
I'm a happy fastmail user, and actually I'd like to see the ability to 'fetch and save images' in addition to the 'show images' button, so that I can archive some of those remote-image-wrap emails.
Remote image links are a bane - look how many forums have been effectively ruined because they relied on 3rd party image hosting, that has now changed it's policy, or gone away, etc.
Another annoyance are the dynamic links to other stories that you see at the bottom of news sites. I often spy a link I'd like to follow just as I leave the page, and then when I reload, the links have all changed! Super annoying.
