I think I'm definitely in the camp of "make a solution that works" rather than "make a perfect solution". Frex, we need a dining room table that folds, not a perfect one (that argument went on sporadically for nearly 2 years but has now been solved); Keith offered to build me a perfect bed, but I got bored of waiting and bought a less-perfect one.

But then I can get wound up by people doing what seems to me obviously sub-optimal things that "work", like unsorted bookshelves, and washing up/cleaning teeth while leaving the tap running.
