A direct e-mail link-- either as a plain-text address or a <mailto:> -- means that every spambot in sight gets instant access to your e-mail address.
As a user I see things the opposite way. If there's a form, the site looks more professional. Any illiterate can put in a <mailto:> link ;) but a form makes it look like a "real" site.
At least up to the point where you click Submit and you get taken to a page filled with Java error messages. (Don't panic. It's nobody here.) That's when the <mailto:> starts looking good again.
