This is simple economic mathematic. The simple problem is (and that`s what you do NOT learn at University
), you don`t know all parameters: How many Amps will customers use, need, wanted and how much are they willing to pay.
The difference to the toner/cartridge is: There is no consumption once you buyed an Amp. Cartridges are supplies, Amp-Sims not. This change the calculation basis a lot...
Normally you`ll calculate an average revenue per unit (street price). Because the marginal cost per Amp-Sim is nearly zero, you loose profit in the first line, when selling the unit for less, to lower the potential buyers barriere.
This concept works, if you get enough consumers buying so many additional Amps, that the assumed average revenue could be reached (break even). Some will buy no additionals, resulting in a underperforming revenue, some will buy more, resulting in a overperforming revenue.
This concept give you the chance to scale unit production because of lower entry level, resulting perhaps in lower production price per unit and in fact a "floating consumer price", because consumers pay what the want or are willing for (through accumulate additional extras like Amp-Sims).
This COULD be a winning concept, but the risk of miscalculation increase, because of entlarging the amount of unknown parameters.
Technical issues like update process, sim-protection, etc...ignored...
