Well, chip-in-cartridge + green light on handle = completely new equipment throughout (power supply, handle, cartridges) even if the components are likely all backward compatible). Too bad, the ecosystem had been very stable for years :-(
Good way to generate more revenue and create more distance with Thermaltronics et al.
We'll see in practice how this whole technology plays out. None of their material goes into any detail about how it works. Possibly just looking at the power and temperature curves and "seeing" the phase change which must have a distinct signature (e.g. temperature briefly doesn't change while power is still pumped to the joint). Now, how is this sufficient to declare a joint "good"...
