I use the signature because it's a way to identify myself to others - they know that's a valid signature and message, that malware won't be able to use the signature from the certificate storage, etc.
Also because there's no "I said, you said". If you get my message and it's signed, the e-mail client will tell you if it's been tampered in any way, so in any case everyone knows that the message is true to the original form.
When I was working in the big mean cubicle world, the big corporate company, my co-workers wouldn't understand why I was creating PDF files to send to clients, instead of simply sending the Word document - which everyone knows contains more information than we may want to disclose.
It's all about information security and management, really.

some of my clients (humans, not software) will not accept email unless they're GPG signed.

I use GPG signing and it seems more common than S/MIME signing (by my own observation). The idea of paying to have an S/MIME key signed by one of the major x.509's doesn't appeal to me.
