Why is an iPad Pro not a Mac?
It doesn’t run OS X.
Why is an iPad Pro not a good Mac?
It has but one port (which doesn’t connect to much), and limited amounts of RAM, storage, and battery.
What fixes that?
A dock, which uses the Smart Connector.
Thunderbolt 3 ports are also USB-C ports. Imagine four-to-six of those, and maybe still HDMI and SDXC for the time being.
The MacBook line becomes redundant.
RAM and SSD by themselves?
Doesn’t sound like Apple.
So, not only do we get a dock which turns an iPad Pro into a sturdy notebook, but we get a functional Mac even without the iPad Pro attached. There goes the need for the Mac mini or iMac to exist.
But the $pice from Mac sales must flow!
If the only way to dock the iPad is into a Mac with the same year’s processor, Macs will be purchased more frequently.
Today’s 12.9″ iPad Pro probably represents what will pair with the average consumer’s Mac. What should we expect, then? That today’s iPad becomes just a little bigger, to be the head for the smallest Mac, and we get one more ginormous size on top of that?
The iPad and iPad mini of today might stick around, but they don’t seem like candidates for docking.
