I don't think people are reading the very closely before responding and it was just a side-note anyway. This is NOT a unit issue. The device has EXACTLY 29,260,513,280 bytes -- 29.26 billion and is advertised as "32GB". That is a difference of 9%. Yeesh. GB = gigabytes by giga is defined in SI units meaning 1000^3, GiB = Gibabytes 1024^3, which to my knowledge has not been adopted by Système international. However, I'm more interested in discussing the regression(s).
