As Superchargers become more ubiquitous along highways it will be unavoidable for some local owners to engage in daily Supercharging. Personally I see that as a waste of my time since nothing is more conveniently located than my own garage. For a few dollars its not worth it to me to have to drive even a few miles to a Supercharger. I used to do that when I had an ICE and now I am totally spoiled.
With regard to destination charging, this needs to complement Supercharger networks. In particular, overnight destination charging is very important, and it is a low-cost supplement to expensive Supercharging.

It is also worth noting that while the battery temperature is indeed controlled and cooled/heated as necessary - if you are concerned about
decreasing range over the years, supercharging every day is likely to accelerate that effect. Slower, overnight charging is better for the battery, and - as far as I know - keeping the
charge between 20 and 80 % when possible.
I wonder what would happen to the battery of a Model S if you
exclusively charged it with superchargers. How would the range of that car be after 8 years, compared to a car which was mainly charged overnight at home or work? If Tesla Motors are sufficiently smart, they will be
logging which car charges when (in superchargers), to gather more knowledge on this over the years. If warranty issues start coming in over the years, before the 8 years are up, they could look back at the cars charging data and see if extensive supercharging was the cause.
Superchargers were never intended as a daily charging solution - I wonder if there is any
small print somewhere about this, to void the warranty or at least use it when people complain after 7 years and 11 months that they
no longer get the range they paid for initially. I could imagine Tesla Motors using individual supercharging usage historical data in certain cases to explain a car owner why he only has - say - 80% range after 8 years and 200K miles.
There are owners of the Model S who are
neither able to charge at home nor at work, a good example is Hong Kong and London. Superchargers in Hong Kong, where two are already operational now (and have been since Signature launch less than three weeks ago), will be used extensively by city dwellers, possibly even myself included to some extent in the beginning of my ownership. The local parking garage haven't made a decision yet, despite me asking them for more than 5 months now (I should get my car in a month now, and there still isn't any solution). There is a 13A/220V charging spot close by, which costs 3 USD / hour parking. That is two days and 150 USD roughly, to get a full charge - not really the perfect setup, even for someone who doesn't drive that much.
Destination charging, especially public parking spots, is surely the next centre of attention apart from superchargers. Slow chargers should just be available everywhere and included in any existing parking charge, while it would be OK to charger (haha!) a reasonable amount for a high speed charger. A place like an airport where you are likely to be parking for days or even weeks, cheap 2kW installations to keep your car plugged in the entire period you are gone would be suitable (although not very efficient compared to a 11 or 22 kW charger).
