So much news came out during Steve Jobs's keynote yesterday that it's hard to assimilate. But if you want to get your head around it, I think the key idea is that iOS 5 and iCloud will cut the cord. it will no longer be necessary to connect your iPhone or iPad to a computer in order to put music on your device, sync contacts, update software, etc. Steve Jobs refers to this as the post-PC world, and Apple is giving us devices that are free of the PC. AND it's free! And automatic! And turned on by default! You don't need to think about it.
