You know; I'm not super-excited about MMS, but it will be nice. And here is why.
I send pictures and screenshots to my dad constantly (once a day maybe) to his work e-mail from my iPhone. Unfortunately, his Blackberry cannot see the pictures, so he has to view them on the computer. I also would like to be able to send these same pictures to my mom and sisters, because they rarely check their e-mail.
I will use MMS... but I am not super-excited about it.
So to the person who said it gets old fast: It may for you, but for others it's useful in showing people things in your everyday life.
Blackberries can't handle PNG images? Wow, I thought they had the best email on any phone
