Good rant. Thankfully it’s a tweetstorm not some readable blog post. 😉
I think about this kind of thing with cable box TV UX. At my parent’s house, changing the channel takes like 4-5 seconds for the new channel to come in with all the overlays and garbage. You used to be able to turn a dial and the new channel was instantly there.
You’d like to think performance is a steady march forward. Computers are so fast these days! But it might just be a steady march backward.
