Apple Releases $49 Thunderbolt 3 to Thunderbolt 2 Adapter Alongside New MacBook Pro

And add that USB-c (3.1) has a 10gbps bandwidth vs thunderbolt 3 that has a 40gbps bandwidth. That's why it's required for the 5k display.

- Not really. The USB bandwidth of 10 Gbps isn't relevant. The DisplayPort 1.2 bandwidth of 17.28 Gbps implemented in the port is. That's constant whether the port uses USB 3.1 Gen 1 at 5 Gbps or USB 3.1 Gen 2 at 10 Gbps.

Forgive me-it was more to demonstrate the difference to the previous poster "of they lol the same why don't they act the same" where protocol and bandwidth are important differences.

You should probably put this into perspective:

The iPhone 7 is going to sell over 200 million iPhone 7, not to mention the over half-a-billion Lightning devices already out there the same cable can be used with.

Apple will likely sell around 20 million Macs, all together, this year -- not just the new USB-C models. Compared to the installed base of maybe 100 million, maybe 10% of all Macs sold by the end of the year will have USB-C only ports. So that works out to be something like 2% of all iOS users may be using a USB-C Mac by the time the next iPhone comes out.

So instead of giving the vast majority of customers a cable that will be most useful in all of the environments they may encounter throughout their day, you'd have Apple supply them with a cable on the less than 2% chance they will buy a new Mac?

Glad you're not running Apple. ;-)

Looking at it that way, the smart thing to do would be to include an adapter with the new MacBooks. Many people already have USB hardware, and very few will be upgrading their printers, external drives, cameras, or headphone for that matter to USB-C. I can't believe I just endorsed another adapter...
