content: Bluetooth is just another way to fuck people Bluetooth is being upgraded every year. The problem is that the hardware you already have cannot be upgraded. This means that you have to buy new hardware almost every year in order to have Bluetooth up to date. I am talking mainly about smartphones, headphones and receivers-transmitters. Your Bluetooth headphones are worth shit the next year. Imagine if you' have bought quality headphones starting from about $300. Good luck finding a sucker who will buy it.
