What I'd do with the device? I'd play with it, tinker with it, hopefully not break/crack it, and see if Samsung can win me back over Nexus and Nexus-like options like OnePlus/Motorola with their relatively clean ROMs.
I'd use a new Samsung as my daily phone, enabling me to take the plunge and CyanogenMod my S4 without any fears. (I think time is the real reason I haven't, not fear per-se).
I really would love a new Samsung. I hope that they have SD cards, but regardless, my phone is getting old and I see the S7 or Nexus 6P as the 2 most likely candidates.
I'd love to see a metallic red or blue color. It will probably be the lame gold, white, and black, but maybe there will be one color too!
In reality, my wife will probably steal it from me
I honestly can not afford to pay these high prices for a upper tier smartphone. With that said, an upgrade to new technology would be great as I still use my LG G2 as my everyday phone.
I haven't owned a Samsung since the Galaxy S3 but this phone looks like its gonna awesome! Especially if they boost the battery and make it waterproof. It would be an amazing phone to have.
I think my HTC One M8 is starting to act weird.. Takes a couple plug-ins to get it to start charging.. Seems a little slow even though I cleaned most up. Wouldn't mind replacing.
Would like to try a new Samsung again with interchangeable battery or SD memory card. I had a note 4 but I quite updating to note 5. (no SD or battery swap able). Would like a gold color if I am going to win one.
Not sure what I'd do... but it would be nice to have an unlocked phone again. Of course Black will be available but it would be nice if Samsung released some colors other than gold or white.
