I like Jaakko, and some of what he says, but the logic displayed in that particular article is about as wonky and prescriptive as that applied by MS to the UI in recent desktop OS flavours (butchering menus - Start particularly - and Metro).

He even talks about screen burn-in for goodness sake, and moreover it's his first point! What decade is he living in? LCDs don't suffer from it, and neither do recent Samsungs' mobile AMOLEDs nor LGD's TVs (dunno about AUO's OLEDs). Plasma which did suffer, but had workarounds to fix it latterly, has never been used in mobile and is dead now anyway. Emissive Quantum Dot displays will have no problem with burn in either, and they're some years away. I'm certain Jaakko knows this, despite not being a hardware engineer, and he's just hoping to back up a tenuous argument with an impressive technical sounding false premise.
