I think he's only showing the latest devices from each platform.
Not even, really. I just came across that photo and seeing the two families, iOS and Android (sorry, I don't really care for the Kindles, but they were part of the pic...), it just made me realize how amazing the choices are from both leading platforms.
I threw in Windows cause I know it's up and coming and a lot of people are open to the idea. Just couldn't find a nice family photo like the others.
But, I wouldn't take michaeljohn too seriously. His question regarding where the Galaxy photos are had a hint of mockery to it. I'm becoming more and more convinced he's around these forums to troll. It already sounds like he's made up his mind about staying with the iPhone 5 based on his other thread.
We're here to enjoy the good times for mobile tech at this moment.
EDIT: Anyone's free to add whatever family portraits of tech devices they want. :]
