I'm thinking we're getting an announcement in January about the new server farm and the availability of the new product/service will begin February 1 (Xserve ends January 31).
This server farm might be a business orientated project. Companies will no longer need to have servers themselves but can use Apple's farm. This means no more maintenance, updating, etc. and not needing to run a big server yourself it will reduce energy consumption and free up some work space.
The way I sometimes see it is that in a few decades people who have a 'desk job' will no longer need to go to work but will be doing everything at home using the internet. This eliminates the need for big office buildings, reduce traffic during rush hour, etc. Employees will be able to take their kids to school themselves, they won't waste hours sitting in a car, they won't need to spend money on fuel for driving it to work and back again, they get a computer and a cellphone from work and off they go. They will be working at home. Some people I know are clearly getting into this pattern at work. Ad Facetime or Skype to it and you can have meetings etc. on the computer.
Just a thought but I think it could do allot of good.
