No, but then I didn't call the numbers minor.

As an indication of popularity the numbers place MMS in stark contrast with SMS, with the latter obviously used by the world and it's dog, whereas the former is not even in the same league where popularity is concerned, and obviously isn't what many would consider a "vital" feature (nice to have, but not vital).

The number of people that use MMS, when taken as a percentage of the total messaging population (and based on these numbers) could, however, be considered "relatively minor". Which is basically what I said in my post.
