I passed on the Pixel because of lack of mSD card support. Samsung fans were outraged when they removed the mSD card on the S6. People are familiar with mSD cards thanks to Samsung for making it more well known on their phones. Sales associates always mention the mSD card support to customers if they are concerned with storage.
But you're sorta right too, the average person just takes selfies, surf Facebook all day long, and Snapchat friends every minute of their lives. I think built in internal storage should hold enough selfies.
Right but there's a HUGE difference between someone noticing it does or doesn't have a card and someone caring at all about it and then there's a huge difference between it being something they want or don't want to them making a purchasing decision based solely on that single feature. We're talking less than 1% of 1% of people that would be in love with a device and not buy it because of that one feature, which big picture means that it isn't driving sales figures in any way.
