That's the fair way to look at it though. You don't expect to get three months' less warranty when you buy a model three months after release. It's also how the EU software upgrade requirements work: 5 years (or more) after they discontinue the model and stop producing it
And it’s a fair point for me to make that if you want to look at it that way, you need to be consistent about looking at it that way across all offerings.
And that’s 6 years _so far_.
