My newsfeed on Facebook is full of ads of hardware startups with amazing concepts of products. When I get into the "know more" is always a "pre-order". From IOT-retrofit-motorized-shades to triple-your-macbook-screen-via-usb. I've been burned so many times that when I see "startup", "hardware", "pre-order" and "as a service" in the same pitch, I make a mental note of "call me back once you have a real product and it does not depend on your infrastructure".
