Yes, it seems that there is no way to avoid adapters in this new “Apple era”. Those who are very happy about this are probably the designers / engineers, who are venturing into Kickstarter, creating increasingly different solutions (or not so much, but useful enough).
One of these creations is the HyperDrive, whose premise is to free users of the new MacBooks Pro from so many * expensive * adapters “hanging” on their computer.
Connecting to the two Thunderbolt 3 outputs, HyperDrive allows devices with different inputs to be connected to it (making it what it was supposed to be since always). The available ports are: an HDMI with support for 4K videos (at 30Hz), a Thunderbolt 3, a USB-C, an SD card slot and a microSD card slot and, finally, two USB 3.1.
As the 9to5Mac commenting on the device, it doesn’t compromise the charging speed of the laptop at all, being able to release up to 100W, which is enough to recharge a 13-inch MBP (requires 61W) and also the 15-inch (87W) model.
The project has already exceeded the goal of US $ 100 thousand, raising more than US $ 233 thousand with 2,711 contributors. It remains available until January 17, 2017 and you can have a HyperDrive in silver or space gray contributing to Kickstarter from US $ 69 (plus US $ 10 shipping to Brazil).
