ELI5: Why does my 160GB iPod only have a capacity of 148,79GB? Isn't this false advertising?

1. The operating system on the iPod takes up space.

2. The storage is advertised as 160 Gigabytes, which is 1b bytes. But actual storage would be instead measured in Gibibytes, or 1b and a bit bytes. 160 GB = 149.01161993848 GiB.
