Changing form factor is also considers evolution. Tech people tend to ignore anything beyond a list of specs, but something like iPod Nano design creates interesting ecosystem beyond the initial "omg it supports MicroSD", e.g. the iPod Nano wristwatch. I know at least six people bought the iPod Nano because of that and they will probably never considers buying one if Apple were adding MicroSD or supporting FLAC. (Can't comment about Spotify, Rdio or Rhapsody because they're not available in my country anyway.)
