My wife and a similar gadget and app ridden car, totally ridiculous at times and we both think potentially very dangerous as well. My wife refuses to get involved with any of it. As she says "What is the point of it all?" My suggestion is that the manufacures can increase the prices by claiming the new technology will benefit you in all sorts of ways and the dealers will offer you wonderous stories of what the car can do for you, you knowing you can now own your own space ship and so on. Its a car, rusting metal on four rubber tyres!
With your present phone can you buy a bigger capacity SD card? Thats what I did with my Motorola. It transformed it. The problem seems to be today that the manufacturers seem to be boxing people in, batteries that cannot be changed, phones that do not accept SD cards, no way of securing the phone to your wrist any more and loads of obvious bloatware.
My phones are always Android but I always make sure that I always buy a 2 x SIM card mobile phone. One SIM is for my phone calls, the other is for my internet, or if I'm abroad I can just slip in a local SIM card.
