....Unless you are in a remote location, far from the grid. For most of those apps, lead-acid batteries aren't so bad. Those are normally fixed locations, size/weight are not a big deal.

Yes, but, some of us do have an interest in backup power at cheaper cost. If in fact the 52kwh super-cap was $3200 and moving towards $2100, then it would be a lot less expensive than the $4000 or so that I paid for a 17kwh backup battery bank (only half of which can be used regularly, or 80% of which can be used rarely - in order to ensure a long life). Lets see, 47 cents per regularly usable storage capacity watt for an AGM battery bank, or 4 cents per watt for a super cap...not too hard of a decision...but only if it works and the bugs are worked out. I for one would really enjoy having 52kwh of storage for my 12kw array. It would mean I could have all the power I wanted, any time I wanted, when the grid was down.
