There's only so much innovating you can do on a laptop or handheld device. It's time for Apple and the rest of the big tech companies to start focusing on moonshot ideas: like teleportation, trains, transportation, perhaps even an iHouse. The iHouse could be a modular unit that can move around the city when you need to move, thus plugging into any other iInfrastructure areas, making moving much easier and reducing commutes, saving the environment and huge amounts of time and money.
Unfortunately, no company will be able to do the above, because government prevents all of that from happening. The next 100 years will be a period of great innovative stagnation, until people and voters understand that innovation must first be legalized before it can occur. And we haven't even begun to educate voters and politicians on these matters, so it's going to take a looong time.
