Can't live without this Puntuado con 5 de 5 estrellas
This is a must have it tool, just imagine for a split second, you are accessing computer in different place e.g. office, university/college, home, friend's home etc etc and want to have your bookmarks available everywhere, this is a tool then.
Not ideal if those machines are in public area i.e. not your personal computer or personal profile on computer e.g. at university.
