there are still a LOT of people that don't have email on their cell phones. there is still a weird disconnect between some people's phones. some phone (iphones and more) can't receive or send picture messages, many don't have email. i suppose the issue is when you try to send a picture to a few people at once. say you have something like a Treo that supports picture messages and emails. you have to split the people up into delivery options. If your Treo is on Verizon (like mine is), then they strip out all incoming email attachments if you use the built-in email client... and being Verizon you do not have the same 3rd party app options as other people.
Yes, it's a first world problem, but it's just stupidity of the carriers. The US had the same issue some years back when you could only send a text message to people on your network. I actually had to think who had the same carrier as i did before i sent a message.
