What's your logic.
The price of Sonar has remained about the same year after year. Meaning, the price of Sonar 3 of tens years ago is the same roughly $500 as todays. Which then means, adjusted for inflation todays price could be $800. Even though the new buyer today is getting a whole lot more for a downward adjusted price of $300, as per a Sonar 3.
Gee, perhaps if everyone follows Walmart and raise the wage index, quit fighting bloody wars, and invent technologies to make the digital realm more secure...........perhaps it will soothe your logical emoticon.
