what it's said there is not very accurate. I would consider that text
as FUD. "Hey, don't do it that way because if you do god will kill a
kitten each time".

Actually, PGP-MIME is a recommendation by OpenPGP to ensure easy of 
use, interoperability and standards. It's better? I wouldn't judge it
but not necessarily.

But is not as it's being told in that page. In years (over 10) sending
inline PGP messages I had 0 problems of the related in that page.
Indeed, PGP-MIME messages are armored texts but in separate blocks to
conformance with MIME itself. Nothing else, nothing of magic.

We talked about this in the past few weeks/months in the list becasue
another user had these problems. Sylpheed only understands PGP-MIME
for decryption. Can't decrypt inline PGP.
