I guess I'll chime in. I owned a '13 P85+ for about 6 months and moved it along. First off, I'm an SUV type person. I like the additional room and the higher ingress/egress. I found myself very interested in the Model X, but at the time, it was a couple years out. So, I decided to try the Model S as a way to evaluate first-hand what Tesla was all about.
What I LOVE about the car: Persistent internet connection for "radio" and navigation via Google Maps. No gas station visits and always having a full tank (nightly plug-in). It opens my garage door when I approach the driveway automatically. It closes the garage door automatically when I leave. The acceleration (although it does take an adjustment period if you are, like me, prone to motion sickness - even with just normal driving). The gas pedal is also the brake pedal (love!). It preconditions the cabin based on a learned driving schedule (awesome!). You can set the cabin temperature with your phone (awesome!) AND see the cabin temperature at any time.
What I didn't like (besides that it was a car): Very chintzy accoutrements (compared to any other similarly priced car) No place to put stuff other than on the floor tray (no console, no door pockets, small glovebox, no seat back pockets, no ledges, nothing). No vanity light or even a door on the sunshade mirror. Terrible, terrible seats (did not have the upgraded $3K seats) - this was probably the main reason for trading it off. Marginal fit and finish of body panels. Going to TPF from Oklahoma City, I had to make 2 stops of about 30 minutes each way for electrons (although free, still it added a little more than an hour each way to my travel).
I do intend on buying a used X in the future - just waiting for the right strike price. That could change depending on the competition and/or Teslas financial condition. My mind is BLOWN as to why none of the big automakers STILL haven't stepped up to the plate with a similar vehicle.
