Now, Apple is reportedly poised to try a second transformation, enticing music fans to store songs online — "in the cloud" — instead of on a hard drive.

This means if you've run out of hard disk space on your computer but need to keep files, you can store them in the cloud through Jungle disk.

While I always recommend that people keep copies of their most precious photographs on a drive at home — perhaps even in a safe — it now makes perfect sense to also put all of our photos online.
