You mean they should stop working on the OS to save you some "not the latest" anxiety?
Tablets are expensive. I cannot afford to buy a tablet every year. So I want a tablet that is future proof. The 10 inch tablets that others will release this year will have an outdated operating system on them and will still cost many hundreds of dollars. I do not want to spend hundreds of dollars on an outdated operating system. I love Android, but this terrible to the extreme.
But none can predict what's future proof, mainly because it's what companies make their money off. They NEED you to buy a new tablet, phone, etc, every year.
They'd make car breaks and need complete replacement every year if they could as well.
So, while it can happen that a product is "future proof" for a couple of years instead of one, it's rare.
Heck, even clothes are made to break quickly.
Of course, that's not very ecological, and certainly not cheap for the customer ;-)
