If all the storage tiers got bumped up one level, that would be really nice. I know people that are upgrading from a 64GB model and are really feeling the squeeze. 256GB base basically quadruples their available storage, and they’ll be good for a long time. Start at 256 and give us up to 2TB, which is a little more my speed.
Am I personally running out of space on a 1TB iPhone anytime soon? No. But will it last forever? Also no. I’d totally be in for a 2TB iPhone. And you know what? If down the line they did a 4TB iPhone, I’d be in for that too!
