Noticing and whether it matters are separate things. I have an older car, I notice that it isn't a new one every day, but it doesn't matter to me.
That's a bad analogy, the mini isn't old technology, quite the opposite.
A better analogy would be my being interested in a BMW 1-series, when you who own or have driven or want to own a 7-series (760Li), think that the 6 litre engine in that car is the only engine that anyone should ever choose to own, and driving a 1 series is in no way as good as driving a big 7-series with a big 6 litre engine. The fact that some people might like the smaller form factor of the 1-series, and not be so totally enamoured with a huge gas guzzling engine, doesn't matter, their interest in the smaller 1-series is because they are stupid and/or they don't have enough money for the "real" version. The fact the big engine wouldn't fit in the smaller car doesn't matter, anyone who likes the 1-series is still stupid for wanting such a small car with a small engine, and the big point here is that the car is *only* the engine, nothing else has any impact on the user experience except the engine, not the driving experience, the manoeuvrability, the gas mileage, the size, the feel, etc.
This technology isn't old, it's never been produced in a device this small, this thin, this sized, running the way it does, with this battery life, ever before. That's not old tech, that's new. And the experience is wonderful.
