The 16/64/128 GB lineup for the iPhone 6 ensures this is only going to get worse. Why they didn't bump up to 32 GB as the base level is beyond me.
For example, in the past I've always purchased the "base" model. First 8GB then 16GB. But now, for me, 16GB is probably 1/2 my ideal storage size, so I'd probably purchase the more expensive 64GB model.
The new "base" model is effectively $100 more expensive.
