I have to agree with your disdain for forms. I hope that when given the choic ebetween obfuscating an email address and providing a form, our response will be to improve our spam filtering and offer a plaintext mailto: link.

Plaintext links have high usability. The mail is organized within the user's mail program where it can be retrieved, collated by subject, and so forth. It can be copied and pasted. It's the abslute best thing for them :-)
