I reluctantly joined them last year after selling my DSLR and lens collection.

I enjoyed my many DSLR years, but recently its become problematic :

     1. The whole personal security thing, the world has changed and not in a good way.  The number of places you can comfortably walk around with $$$ worth of camera kit in a bag ... LET ALONE take the camera out of the bag without needing eyes at the back of your head is decreasing FAST.

     2. I got sick and tired of being subjected to secondary screening at airports in certain parts of the world where the security guys are not used to seeing a bag of DSLR kit and/or it being a country where they are "sensitive" about what long-lenses can be (theoretically) used for.

     3. The whole insurance thing has become a pain the backside.  Premiums constantly increasing, but more importantly, so do all the get-out clauses which means you struggle to find a policy that deals with the reality of traveling with cameras.
So, yeah, previously I would sneer at the iPhone brigade. Now I've joined their ranks.
