Yeah, like all tech, if you let them, eventually some exec will decide to play hardball and offer a cheap (to the supplier) fix at a price just low enough that you will not replace your whole system, but which lets them charge a hundred times cost or more. I’ve seen it happen so many times with software. There was a company (Computer Associates, IIRC) that went around buying up other companies that were not taking advantage, and then pulling this trick. They’d raise the maintenance and support contracts up higher than the original purchase price because they new what it would cost to rip it out and replace it with the competition. They made huge profits.
I’m guessing that will happen to all the Garmin glass out there. Watch out if they sell the company.
