Interesting article about speed of modern computers

Interesting article which draws our attention to the fact that modern computers react to keyboard input slower than old ones (i.e. it takes more time from you hit a key and before it appears on the screen).

Main reason is that there are many more levels of abstraction between keyboard, text editor (which also became more complex), and screen - imagine OS, device drivers, multiple concurrently running applications / windows, etc - and many of this running asynchronously.
