> It's really perplexing that no one including the Chinese are trying to disrupt this industry No point. 1) Low volumes These things never really go obsolete and the replacement rates are abysmal. 2) Race to the bottom Once you disrupt it, everybody sees that you disrupted it, and everybody clones you and piles in. Customer support is the only differentiator. To fund that, you have to charge north of $10K per unit--generally north of $25K. Tektronix found this out the hard way with their real time spectrum analyzers. It was a nice disruption at the $5K point. Lots of people bought them. Then demand dropped like a rock because everybody who needed one bought one. And because the revenue crashed Tektronix laid off the development group--who are also the same people you need for advanced customer support.
