They aren't the same model. And the 2016 model is probably better overall since it has better technology inside it. Speed definetly isn't the only thing you are looking for in a car. Meanwhile in tech world a keyboard is a keyboard and you can't improve but add LEDs and charge it double. It will also break after warranty expires while older products were much more durable in my experience.
Both cars represent the top of the line sporty model, both use the same engine, one got loaded with gizmos that make it heavy and slower, the other is simple and because of this faster. Speed may not be the only thing YOU look for in a car, but don't generalize and say it's not important because it fits better with your argument.
No, a keyboard isn't a keyboard as a matter of fact, LEDSs aside, a standard bundled keyboard vs a mechanical gaming keyboard are two very different things, one is cheap and flimsy, no rollover, the other has tactile feedback, the ability to press multiple keys simultaneously that all register and in general provides a better experience. To then say it will break after warranty is more BS, do you have any numbers to back this up? I've NEVER broken a keyboard, I've accidentally spilled stuff on them, dropped them, abused them in general and they all still work to this day. Someone ragging out and smashing one doesn't count against the manufacturer either.
