And I hate this argument. I don't keep track of what service every one of my friends uses. Who does that?
And if I'm in the middle of a text conversation with someone, having to switch to e-mail, and then tell them to check their e-mail (which they may or may not be able to do immediately) is far inferior to continuing the conversation in the original medium, which is SMS/MMS. What is so hard to understand about wanting to be able to send a simple picture or media file to someone--anyone--with a cell phone?
And there are plenty of people in my life who, while they have e-mail, only check it for work reasons or every few weeks. They're mainly the older people in my life who do have MMS-capable cell phones, and would appreciate a quick picture or video from me.
Regardless of whether you (general you) would use it, there are plenty of others who would. Obviously, it wasn't a deal-breaker for me, since I got the iPhone with no promise of MMS, but now that Apple got off its high horse and it's available everywhere but the US, it's a bit frustrating waiting for AT&T to get their act together.
That said, it's nowhere near "late summer," so...
Hey I'm not saying that is the most efficient or convenient way of doing it. But, if you must send a picture to someone that gives you an option. Also I only need to remember t-mo and att because that's what my friends use so not to difficult. I was just giving an helpful suggestion to OP to help ease his frustrations with waiting. We are all waiting and know its late summer so just deal with it for the time being and when we finally get the ability it will be easy, convenient, and hopefully error less.
