Unlike Thunderbolt, USB-C is an open standard and we'll see lots of new products with USB-C as time goes on. SanDisk has already announced a USB-C thumb drive. So, what kind of USB-C accessories would you like to get your hands on? I'm not talking about adapters, but actual products. I guess these would be things you already own, but would have USB-C natively. Just another way to get us to spend money! The only time I ever plug anything into my rMBP other than to charge my phone is to use my external Blu-ray drive. I'd love to see a USB-C external Blu-ray drive, but I'm not sure if it'll ever come to fruition and if it does it'll take a bit. So an adapter works just fine for now. USB-C monitors in the future sound cool as well. And maybe in 1-2 years when USB-C is widely adopted, we'll see USB-C hubs similar to the USB/HDMI hub is Apple is going to be selling for $79.
