I stopped wearing them 2 years ago and don't miss them at all. Of course I still have some and will put them on sometimes when its practical, but modern denim just doesn't seem to be as hard wearing as it used to be, and I'm also sick of the weight and poor fit.
I was especially annoyed a few years ago to find my favorite brand had slightly shortened the zipper, thus eliminating the whole benefit of being able to pee standing up because it was difficult to get my hand inside the smaller opening and uncomfortable to have it pinching me while I use the toilet. I'm sure the small savings on shorter zippers add up in the corporate accounts, but why would you make it more difficult for half the population to do something they need to do multiple times a day? They do the same sort of things with women's jeans by making the pockets too small to fit anything into (not to mention all the problems of getting a good fit since women's body shapes seem to vary more than men's).
Economically jeans are an interesting example of commodity fetishism systematically making the product worse, as the emphasis shifts to fashionable display over comfort and functionality, and eventually the latter begins to be sacrificed in pursuit of the former. The oddest example I've seen of this was a UK startup that proposed to give people free jeans for 6 months or a year so that they'd wear them in and then ship them back for sale at a high price to fashionistas who wanted an authentically distressed look rather than one inflicted with a power tool at the jean factory. In other words, people will pay money to look poorer than they actually are.
