Okay, you asked.
Nearing 10 years ago, it was marginally understandable how there could be manager types who’d see the on-screen flipbook thing and think it was so nifty that it’s unquestionably must-have.
If that same scenario still happens today, I’d say it’s a sorry commentary on how far we’ve not come. Personally, I think the things are an insidious gimmick; a waste of time and effort for both the originator and the target audience. Over that same 10 years, rich, lustrous UI design fell out of fashion in favor of flat, lifeless circles designed to invite fingertips to the touch screen, yet a meaningless, often inconvenient, simulated page-turn somehow endures. I don’t get it. I remember an analogy from somewhere suggesting that the idea of a device screen used for simulated booklets is kind of like unplugging a power saw to use it for slicing bread.
