The fact of the matter is, with more and more devices releasing with the ability to record 4K video, 128gb storage could EASILY be filled up. Android is about having options.....the fact that the option is there for people should make everyone happy, regardless how each of us use our device.
It's a smartphone FIRST....most users don't even hit or come close to the 32GB limit as it is (I'm in that group)
Key word was planning. Most people aren't going to set out with the mission in mind of recording an hour of 4K video on their phones but I've taken a couple trips recently to Niagara Falls, Chincoteague Island and the Wildwood shoreline in New Jersey and in each trip I racked up more than an hour of combined video along with many dozens of pics. With 4K video and 21MP images that would break the bank very quickly on a 32gb device. I will however definitely be getting a USB OTG MicroSD card reader and bring along some extra cards once I have the Turbo.So, for every minute of 4K video you use 1GB. On my 64GB phone I usually have 47GB of uncommitted storage. I have to say that in a pinch I could grab plenty of 4K video, but If i'm going to shoot more than 10 minutes of 4K video I'm getting out my dedicated equipment. If you actively plan on shooting more than 10 minutes of 4K video and you're planning on doing so with your phone, you're just using the wrong tool for the job.
You guys who say we don't need 128gb of storage are forgetting how much space 4k video takes. In this case let me remind you that 1 minute of 4k video takes up 1gb of storage. Do you want to be limited to 5-10 minute videos before you have to upload? Didn't think so. So 128gb+ is valid as anything else.
Two words: USB OTG
Or is that six words?
Anyway, I have a 128G stick plugged into my Moto X for movie watchin' when I'm commutin'. On board storage is not a necessity for us rooters and unlockers.
That's just so damn unwieldy to have that thing sticking off the side or bottom of your phone...
