Well of course its anecdotal but being that 90% of my peers are professionals here in the city either in creative or business I can literally count the number of folks I know without a data plan on one hand. I would say that its iPhone first and then blackberry bold next in popularity and so sending pictures via email is easy and immediate with all of them. A sign of the times which directly corresponds to your statement however is that I have had three different friends ask me about the N900 as I'm known as always having Nokia phones. This is the first time any of them has ever asked me about a Nokia phone in my life.
