Recently, hardware companies have been popping up in all kinds of places. Nest is building the next thermostat. Sonos sells seamless and beautiful soun systems. Thalmic Labs and Leap Motion are innovating in alternate forms of computing control. Electric Imp is building the platform-as-a-service to connect devices to the web via Wifi and so on. Hardware investments are blossoming because software is reinvigorating the market. Hardware companies face deeper logistical challenges, greater likelihood of margin erosion, and more complex go-to-market strategies than their software cousins.
