Flexibility...

…because of number of products and vendors

…because of the variety of services (peer-to-peer, high speed I/O and hazardous area)

…because of the possible network topologies (line, tree, star, ring)

…because of the number of stations you can connect, the distance you can cover and the amount of data you can transfer

…because it is easy to expand an existing network
