Right, my bad. Bottom line, don't ever buy the 16 GB "six".

Get the 6 simply because of screen size, you'll hold someone's 5 or lower and wonder how you ever survived on such a small screen. Plus the A8 chip makes it worth it in the end in terms of speed. The 6 could easily last 3-4 years if kept in good shape due to its performance. It's a no brainer, imo.
