I use an adblocker, so it's hard to know what ads do (though I disable it on some sites that I believe to be reasonably trustworthy about ads, and that I want to support, like reddit and some major newspaper sites; though I tend to pay for a subscription for sites that I really want to support and continue to block ads).

But, generally, it's fine. Most sites are entirely usable. There's a few that are quirky, but generally, modern websites are designed to scale down to tablets and phones, so they don't act too weird for a narrow lapptop/desktop browser.

I think the most common problem is sites that switch to hamburger menus at too high a resolution (so I get the mobile hamburger navigation on some sites, even though it's kinda silly looking and slightly less ergonomic). It's not super common, though. Most switch to hamburger a little lower than my browser width.
