I'd do the same stuff I do with my current device: Make calls, text friends and family, stream music, take pictures, social network and feed my  Android Central addiction.  I wouldn't say I want this REALLY bad, but it would be nice to win a NEW device.  I'd sell my S6 Active and get out of this NEXT program for sure.  I've always rolled with grey or black devices because I don't like committing to a specific color.  If I want color, I'll buy a case.
I guess my chance is as good as anyone elses.
