What will be the Apple’s NeXt Big Thing. Can Apple pull off the most important product introduction of maybe all time? I believe so and here is why!
3D printing technology is at the same point that the personal computer was when the Steve’s were beginning to produce the Apple 2. That little packaging of computing power unleashed a wave of industrial growth not seen since the utilization of the Assembly line at the beginning of The Industrial Revolution. The technology for 3D printing has reached a cost factor approaching a pro consumer level. Like the laser printer introduced by Apple in 1984 the 3D printer would benefit from Apple’s unique ability to simplify and commoditized the product. Apple also uniquely processes the ability to build the subsystems for unifying, developing and distributing software.
Macintosh Pro Computer line (trucks) would find a new life as a leader in industrial design and production.
