On my last two trips I made it a point to observe what phones/tablets people were using. At first I saw 3GS and 4 everywhere. Then I noticed one thing - the other people pulling out their phones to make or take a call - and coincidentally or not - every single time the phone they pulled out was Android or Blackberry. I think Android and BB people are less OCD and just don't seem to flaunt their phones without reason.
