Chips seem to be around 25mm sq, and the smallest features around 10nm.
If you scaled up so the smallest feature is one mm then the chip would be around 2.5km square. (over 1.5 miles on each side)
If the smallest feature was about the width of human hair then divide the above by 100.
Well, not really - not more -, because we have mobile devices that are born with Android and installing a Desktop Linux on them would be a hassle of doubtful results, and we have Desktop Linux applications that are missed in the Android software availability...
Both ways are sought: running Linux applications on Android and running Android applications on Linux and elsewhere.
Unlike Apple Nokia built their devices to resist breaking and be 100% serviceable down to the smallest parts.
Apple uses metal because it's significantly heavier than plastic and makes phones heavy enough to shatter glass screens and damage their internals when dropped.
Any iPhone could replace its metal housing with an equally strong polymer and become exponentially more difficult to break.
The 3210 era devices had easily replaceable polymer covers; they definitely did break and scratch, but these operated as disposable ablative shielding for the phone itself. Which also had a much smaller screen that was away from the corners of the device. So what people do nowadays on all of these devices is add third party cases to absorb the everyday wear .. but you can always take the case off for a "dress" phone, which like party or formalwear trades durability for looking good.
The Nokia 1040 (Windows, glass screen) was also pretty good at damage resistance. My wife stuck with hers until the Flash started wearing out round about five years in.
> Metal is of course more shatter resistant than polymer.
Yeah, but that doesn't help when the phone lands with the glass hitting something. And a heavier metal phone will have accumulated more kinetic energy during the fall than a lighter plastic one, so have a greater probability of shattering the glass.
Ah, the strong load bearing case and impact resistant glass are just a clever rouse! Their real purpose is to...break more easily! It makes so much more sense now.
Their real purpose is to look "premium". How else would you explain the use of glass on the back of the phone? It's certainly not ergonomics - there are materials that are both stronger and grippier. But it's certainly shiny.
iPhones are built with super tight tolerances. Using the same (or similar enough) materials on opposing sides means not having to deal with different thermal expansion properties. Glass is also radio transparent which makes the NFC radio and wireless charging much easier. It likely doesn't hurt with cellular and WiFi reception either. It's also not going to interfere with the MagSafe magnets.
Somehow Android phones manage to do NFC and wireless charging just fine without glass back panels. And tighter tolerances are exactly that - "premium look".
Tight tolerances are premium construction. Loose fitting parts are cheap and easy. They also lead to increased wear and decreased durability. Dismiss everything as "looks" if you want.
Have California cell networks gotten to the point where they'll be able to handle the mass calling that follows disasters? Curious how people will contact emergency services and friends/family in the critical time following an earthquake/fire/etc.
Not if the power goes out. Unlike landlines (which are required to have generators at the central office), cell towers are only required to have a battery backup that lasts a couple hours.
When we had the rolling blackouts in the bay area a few years ago, Comcast's cable network was the first to go, but the cell network didn't last much longer.
for the most part, things are much better than they were 10 years ago. you can go to a baseball/football game and your phone works. you can go to a concert and your phone works. a big part of this has been capacity upgrades, protocol upgrades, and a shift from telecom traffic to internet traffic
it has always been difficult to contact emergency services following an earthquake / massive fire. it might actually be more scalable now. and you have more options of who/how to contact
My dream has always been a toggle that switches between traditional loud sportscar exhaust and something on par with a stock BMW exhaust. Last time I checked physical switches still had a tendency to leak. The battery method could be the answer to an on-demand lower profile option.
This is super common, but the sound changes are less dependent in the exhaust and more dependent on the tuning.
In the simplest case there are exhaust cutouts that reroute the flow from a button push. Mercedes aftermarket mods are common here. But, there are also tuning changes that can be triggered in the ECU or timing changes in the valves, turbos, and other parts of the combustion flow with digital or analog input.
For instance, current EU emissions requirements keep a Ferrari F8 much quieter at idle than a 458 or 488 but it still can make the fun car sound at full throttle or with aftermarket modifications.
Look into the car you like to drive, there are many mods available, YMMV.
