Those who frequently smash gorilla glass will end up destroying a floppy phone just as quick.
I think I already know from history that just isn't true. My "dumb" flip-phone is hanging in there just fine. I've dropped it a few times, but when Samsung made this in 2006 they used plastic (geniuses! who would think of this?!), and face it: plastic is awesome. This plastic just keeps on not breaking.
My glass tablet lasted a month. I am so glad I only spent $89 on it (no, a $200 one would not have survived better).
It's not even just clumsiness and carelessness, though I won't pretend I'm graceful and always on-the-ball. Some things in some situations just happen to take a beating, by virtue of being in a pocket all the time, going everywhere the user goes. Keys and change constantly grind away at whatever they share space with, dogs jump on laps, my pants-containing-phone get stepped on while getting up in the middle of the night in a tent on a camping trip, stuff is outside in freezing temperatures (and low humidity) and then comes into the house where it's warmer and higher humidity for a while and then goes back out. Shit happens, so much of it and in so many ways.
I don't feel entitled to have "tough SOB" equipment, and if I drop something and it breaks, it's almost certainly my fault. But let's not pretend that stuff-which-usually-doesn't-break wasn't the ubiquitous norm prior to 2007. The very idea that we're all carrying glass personal items around all the time, is actually pretty hilarious when you think of it. The guy who stepped out a time machine from 2006, after chuckling a little, would at least say, "well, I'm sure they break a lot, but I guess the point of this cheap shit is that people don't complain when it breaks, because you can always get another $20 phone to last enough 3 months. $80 a year is a hardware budget I suppose anyone can live with." Then we 2012ers would nervously glance around at one another, wondering, "Who is going to tell him?" Fucking time travellers. They always make me feel so uncomfortable.
