Why do you want to inflict an annoyance and deliberately waste 0.1 seconds (or whatever amount you deem appropriate) of everybody's time? Slowness should be a deliberate, individual choice. I'd be happy if there was a global cfg variable in the OS or browser, where you indicate the amount of pointless, "feel-good" slowness you wish to have in your interactions with any UI element, then you can have your way while I have mine too. I want things as quick as possible so I can race to idle sooner!
