Reminds me about the painful discussion between people asking still for folders and others moving on to tags and categories.
There will always be some people living in vers. 1.0 and crying about changing things and others who see the advantages from 2.0 and "live" them.
I can see no point in trying to explain the advantages if someone tries to ignore them. There are still products wich are doing it the "1.0 way" like using pages, folders, mp3 players with the option to simple copy&paste files ... get yourself one of this.
Locations are one of the best inventions in ebooks they make life so damn easily (especially for readers or books which don't support synchronisation).
