I'm still using one! And it's fast enough for what I do with it --- mainly native development in C, but also the usual communications: email, IM, watching videos, reading content-focused web sites (not web apps), etc. Since I don't use anything bloated, 4GB of RAM is more than enough and the HDD remains silent most of the time.
I experience far more delay and frustration using a much newer, ~1-year-old work laptop with much faster CPU and several times the RAM, but with Electron apps or any other "modern crap" that has a fraction of the functionality. The most vivid recent example is the YouTube "new design" --- it is disturbingly slow and dumbed-down. On this new machine I still experience lag often when interacting with bloated JS web apps, which can't even keep up with my typing speed (web-based Outlook is a notable example of this.)
Even presumably-native applications are not immune to this cancerous growth. UWP is another example; the Win10 calculator somehow needs a loading screen, and so does the Settings app, whose featureless pathetic excuse of a UI somehow manages to be less responsive than the classic Control Panel, which opens basically instantly and is just as responsive to input.
