the benefits customers would have if they could host itunes, business and finance help

Apple is condering a cloud version of its iTunes software that could possibly provide a host of new services for its users as they would no longer be required to save iTunes to their computers as it would reside in the cloud. With cloud computing, the software for iTunes would reside in centralised servers in data centres, rather than on a specific  user computer.

1/ what would be the benefits to customers if they could host itunes in the clouds and access it using a variety of devices?

2/ What would be your fears if you were to use iTunes in the cloud?
