iCloud announcement
iCloud won't be the biggest announcement.
The biggest announcement will be that iCloud will replace all existing Apple products. Macs, iPods, Apple TVs, iPhones and iPads will be compressed into a single chip the user will have implanted at the base of the hippocampus, giving the user complete and intuitive access to the Internet and Apple's NC data center.
This will make way for a new type of profession known as "couriers". They will carry sensitive information for political groups and corporations. The side effect of the implant will prove to be the loss of a great deal of long term memory.
In the near future, Apple will introduce an upgrade known as a "memory doubler" which will prove to be unstable and may cause permanent brain damage. This upgrade will be taken off the market, and never heard of again. Until, a long term side effect of the implant will appear, causing wide spread neuro-breakdowns.
A cure will appear and a heroic courier will use the upgrade to carry the cure into the right hands. His name: Johnny Mnemonic.
