Stewart Alsop II in 1988 said "It is testimony to either the luck or vision of the original designers" of Finder that "the interface has been able to survive tremendous evolution without much essential damage" from 1984. He praised its spatial file manager as "probably a more complete definition of a PC-based universe than any" competitor, with users able to seamlessly use floppies, local and remote hard disks, and large and small file servers. Alsop said that even if Apple had stolen Xerox's technology for Finder, it was now very different. While criticizing the lack of a right mouse button and MultiFinder's clumsiness, he concluded that "Apple remains the king of user interfaces. Finder is the only interface with 1.5 million people sitting in front of it daily. Apple is spending tremendous amounts of money on both development and basic research to remain the leader".[7]
