While there are Android devices who still come with 16GB, most flagships have moved to 32 GB baseline and may or may not come with a micro SD card slot on top of that.
Apple's devices with 16GB are actually legitimately painful to use after about a year or more. They really are ruining the customer experience, and I bet if Jobs were alive they would have moved to 32GB long ago.
It isn't like Apple needs the money.
