I'm exactly the opposite.

MMS might be useful sometimes, when dealing with the ignorant and/or people whose devices are from the stone age (but, even then, I prefer to tell people "I can't MMS, send it to my email address") ... but, even just looking at what MMS does, it's a stupid-person's implementation of email (the stupid-person being the one who designed it, not you for using it). Recipients, including email addresses? check. Subject line? check. Message body + media attachments? check. MMS == email designed by idiots.

Further, for any sort of attachment or media file, I want to have it stored somewhere more permanent, useful, and scalable than my handheld (with the option to download/cache it on my handheld).

All of that says to me "email it to me, don't MMS it to me".

MMS isn't just blemish on the evolution of data protocols, it's redundant to email, and email serves that function better. Any device which simply avoids implementing MMS and says "use email instead" is a device that deserves my kudos.
