256 GB is not that much, as long as the phone has good audio playback on quality headphones and the user likes to enjoy his favorite music in lossless format... ;)
i don't think the user need 4GB RAM , 256GB ROM but they don't demand for 5000mah battery for ultra long battery life. & the camera photo quality is worse due to most review , the 256GB i dont think its use as a HDD replacement.
