I have just figured out how to use the calendar on my "smart" phone. I think I was one of the last people in my area to even get a smart phone.
Love the camera on the phone. Now we always have a camera with us!
I have come to love and appreciate all the "smart" technology on my truck... it is approaching 10 years old, and everything still works. I don't think I will ever have a vehicle again that doesn't have a keypad on the door! Absolutely love that, and it has "saved" us many times.
My wife's Ford Fusion has the "auto-darkening" rear view mirror and side view mirror - very cool, and works awesome. The smart phone interconnect system with the car we don't use, played with it, but so far haven't used it. Also, we do not talk or text on the cell phone while driving, so that feature is useless to us (being in the fire department responding to car crashes caused by cell phone use will do that to you).
I don't know about the keyless car systems using a key fob. I've had friends many times run into odd situations using those. So for now I still prefer the old metal key.
What I am seeing more of now are the "knob" controlled transmissions, especially on Chrysler products. Nothing wrong with that (heck, I drive fire engines with push button transmissions), just odd to me. With today's electronic transmissions, there is absolutely no reason to have a shifter on the steering column or floor.
As to our house? Virtually no "smart" systems. I have a home based business and wife works remotely from home 1/2 the week so we are always in and out of the house. We are good friends with our neighbors so we watch each other's property.
What I would like to install are remotely controlled outdoor lights. So when we hear something outside we can turn on outside flood lights without having to go across the house to the switch panel. Also so when we arrive home at night (like from camping trips) we can turn on floodlights using our phones. Still looking into this!
