"Cast Iron isn't for everyone, because you have to keep a season (or layer of heat polymerized cooking oil) on it, or it will rust.  Many, if not most, people do not understand or can't be bothered  to do this and part with them.  They also should last a century or three; a random orbital sander removes even the worst rust and they can be re-seasoned.You really can't do better for overall heat capacity, they are perfect for getting a crust on red meat or just general browning and frying.  If you can keep them properly seasoned, they're remarkably non-stick for a lot (but not all) types of food.  "

"Two design goals in the smartphone have totally outlived their usefulness and have become counterproductive to better form and function 'progress' (as you put it, a weasel-word in design that says nothing).Thin and light.  We got those things years ago.We don't need lighter phones, a bit heavier would allow us to consider materials better suited to the hell most of us put our phones through.We don't need thinner phones than we've had for years.  Sure it drives innovation in component design, but it also drives designers to toss things we're still using like headphone jacks (it's not progress, it's a bad compromise).  Make it a couple mil thicker, give us a better battery and couple other useful somethings.This is a lazy article devoid of critical or original thought."
