I have grown to like the USB-C port on my new MacBook. I bought the matching LG ultra-def monitor that acts as a charging station and a hub, providing 3 extra USB-C ports, one of which I just keep a dongle for USB 2.
Depends on your use. The only ports I don't use on my mac are the Mini dvi. I use both USBs daily, HDMI when at friends, and the SD card slot for loading pictures from clients - and don't want to carry adapters around with me. The loss of MagSafe is another big one.
Kinda defeats the purpose having a nice sleek macbook only having to plug something like this into it
Apple has always been early on technology changes like USB-C, in a couple years we'll look back on this like when the iMac dropped the floppy drive. USB-C is obviously better, it's just a matter of time before everything uses it.
Doesn't really matter if it's better. TVs still use HDMI and most likely will for another 10+ yr. They're just reducing the functionality of the laptop.
My only complaint is the high cost.
