PGP/MIME considered harmful for mobile

[Robert J. Hansen]

Just as an FYI to the list --

On Android's mail application, PGP/MIME attachments are nigh-unusable.
It won't render even the plaintext portions: it has to be downloaded and
opened with a text reader.  If you're concerned about your mail being
readable on a mobile device (which is increasingly important nowadays),
you might want to consider switching to inline signatures.
