I don't understand their business policy, because this move doesn't make sense to me at all - because currently X costs around 120 EUR, and S around 60 EUR, so this S plus will cost around 90 EUR - but wouldn't it be more logical to lower the price of X? They are developing a product that users allegedly want, and they already have one, the only problem is the price and the problem with the battery.
I wonder who would even think of buying an X if they don't need a BT and a battery - well, I would have bought this model if it had existed a few years ago - which means that they are deliberately sending X into history - real geniuses👎
