s6 - sd card
Hope that initial comments are wrong, but its unlikely from looking at these photos...
Completely understand why phone manufacturers would leave out the SD card, as it leaves room for higher profits on their side by forcing folks to pony up extra dough for higher models. However there is satisfaction in knowing my files can be easily removed from a device if needed... this is especially true if the phone craps out and "you" are unable to wipe it before handing it over. This is similar to why I wouldn't use iTunes or others which force you to move your stuff into their paradigm. I want my crap in my control, as often as possible.
Cool or not, any phone without an SD slot is a deal breaker for me.
