"27. Hardware/software hybrids. Most hackers find hardware projects alarming. You have to deal with messy, expensive physical stuff. But Meraki shows what you can do if you're willing to venture even a little way into hardware. There's a lot of low-hanging fruit in hardware; you can often do dramatically new things by making comparatively small tweaks to existing stuff.
Hardware is already mostly software. What I mean by a hardware/software hybrid is one in which software plays a very visible role. If you work on an idea of this type you'll tend to have the field to yourself, because most hackers are afraid of hardware, and most hardware companies can't write good software. (One reason your iPod isn't made by Sony is that Sony can't write iTunes.)"
