I'm excited to see some hardware concepts coming out of YC in the past couple of years. I think that the lean startup model is starting to be much more viable (vs 5 years ago) in the hardware space thanks to low cost prototyping electronics, 3D printing, and small batch size manufacturing.
There are a bunch of hardware startups in this batch. I'm not sure why. Could be just random variation. But for whatever reason it's kind of the hardware batch.
