My experience is that everything is slower than when I first started using computers as a child in the 90's, and it does it worse. You don't own anything anymore, upgrades routinely take away features, and nothing interfaces with anything else.
There are a lot of reasons why building an app on a web framework makes sense, but the fact that I routinely lose access to applications I've paid for because the company has gone out of business or stopped supporting them drives me insane. I can still install Excel 97 if I want to, but I have 0 confidence that anything I've bought from Google will work a year from now.
I mean, there is perceptible lag in character entry that never used to happen. Sure, my computer used to freeze inexplicably, but Atom crashes often enough that I don't consider that a win, and text has a noticeable delay before it appears on the screen when using Atom. Text entry is something I can implement flawlessly on a microcontroller and the majority of applications I use on a daily basis get it wrong.
