This is a radical prediction. I am sorry if I offend someone. Those squares look quite a bit like pixels. Write the code, change the world sounds like they are talking about software. I know this is pushing it, but I think, they may be talking about computers.
The odds are good that any hardware they announce will be a new development platform. I think the odds of a new Apple TV that runs apps (APPle TV?) has better odds. An iWatch would require apps in one way or another, so it has a decent chance. The odds of a new laptop or Mac Mini are low.
Seeing this gave me an idea. What if the new Apple TV and the lower priced iMac are meant to replace the mac mini. Don't laugh...yet, read on.
Current mac mini owners usually fall into on of two categories:
1. Those who use it as an inexpensive desktop. Rumors of a lower priced iMac would make sense for this group.
2. Those who use it for a media center. An upgraded Apple TV with 3rd-party apps would make sense for this group.
I'm not making any predictions. Just food for thought.
