First time wearing them (they got lost in a moving box for a while). So far, I'd say they're decent. They're thin, since they're dress socks, and they don't stay up, but socks never do on me unless they're over the calf length. But they're comfortable and they don't have bulky toe seams, which is good. I'll need to get in several more wears before I can give more than initial impressions.
I have similar thoughts about the beanie as you do. The loose knit isn't perfect for really cold temperatures, and I bet it would suck in a strong wind, but since I never experience anything below freezing, it's fine for me. It itches more than I'd like, so I'm a bit disappointed about that. Most people probably wouldn't notice it, but being bald means a lot more skin surface area, so I'm especially sensitive to that aspect.
