I love my Le Pliage. I liked it before I bought it, but once I used it on a very rainy day, then I really, really loved it.
It doesn't bother me that a lot of people carry it. Actually where I live I don't see that many, but even if I did or they start popping up all over the place I'll still use it.
I think of it as a new classic. It's not like a trendy thing in my mind, it's more like, say, a striped sailor shirt, or flat-heeled riding boots, or jeans. It's something that people buy because it's universally pleasing to the eye and comfortable and versatile.
It's like saying, "Well, I won't wear jeans because everyone's wearing them now..."
At least that's how I think of it.
