You should theoretically be able to apply more torque through a hex or torx, before losing engagement. Best of luck at the hardware store when you're shopping for #10 x 3" long flat head c-sunk wood screws, and finding anything other that Robertson.

I altered your quote to read clearly.
Not sure how old you are but 2 and 1/4 is the same as 2 and 4/16 so a total of 5 and 9/16 is rather easy, no? It is easily shown on a tape so am I missing something?
We were talking about screwing. Please don't make the Mod team take action for some other input. We tend to use hatchets and machetes.
Avoid that going forward.
Learned that one around 1980. Watched my buddy jump up all over his wheel wrench until two studs were gone. He then talked to his Dad...
Dual clutch automatic is awesome. I grew up with manual transmissions and enjoy some heel-to-toe shifting at times (fun and satisfying when it works out). My car of the past eight years has a dual clutch transmission. I don't think I'll ever go back to manual. I simply don't see the point? My car drives like one with a manual transmission but changes gears automatically.
I have driven cars with a traditional automatic transmission. I hate the torque converter. It makes it feel like the wheels are connected to the engine through a stick of warm butter (which is not a horrible analogy for a torque converter now that I think about it). 🙂
I'm curious how you came to that conclusion. You can buy aftermarket cables for your iThingy if Apple's prices don't suit you. You can get the battery in an iPhone replaced by Apple for somewhere around $50. The batteries tend to last pretty long. I tend to get 5-6 years on a battery before it reaches 80% of its original capacity. The older phones still get software updates. Most other companies only give you that level of support for a year or two.

Come over the border. We'll sell you T-10 screws all day long. In fact I have never seen a big deck-load screw with a Robertson. Most house electrical terminals are 3-way, and quite a few trim screws are square-hole.
Cal - I am quite comfortable with fractions, as well as far more advanced math (not just basic arithmetic). I am not the target demographic who has trouble adding fractions.
But as you just pointed out, in order to add two fractions, you have to know much more complicated concepts than addition. You have to know concepts like factorization, common denominators, reducing fractions, and and how to find the lowest common denominator.
Try this: add 1/13, 3/17, and 9/31. Express the result as a fraction. And do it by hand, not with a calculator or Google.
How long did that take you?
See what I mean?
In order to find the LCD, you have to know how to factorize, how to multiply, and other advanced skills. It is stupid to have to know advanced skills (like factorization) in order to perform a simple skill (addition or subtraction). The use of fractions confuses and holds back many people from understanding basic aritimetic concepts, such as addition.
In fact, it's easier to multiply or divide two fractions than it is to add or subtract them. Addition and subtraction are more basic operations than multiplication or addition - but when you work in fractions, the more basic operations are harder to perform than the more advanced ones. It's idiotic.
To add two decimal numbers, all you have to do is line up the decimal points vertically one above the other, and add the individual digits. Far, far, far easier. Just about anyone with a normally functioning brain can understand that.
I've taught trade school math to adults, and the business of adding fractional inches always caused lots of confusion, and large numbers of errors - from adult students.
My wife teaches in the K-12 system. Children have an even harder time learning how to add or subtract fractions.
You are used to working with fractions with certain specific denominators: 2, 4, 8, 16, 32, maybe 64. Because you've worked with fractional sizes like 3/8 and 7/16 for years, you think they're easy.
Try working with fractions that have less familiar denominators. For instance, calculate, by hand: 113/13 + 2/37 - 47/53.
I know that took you a while, if you could find the correct answer at all.
By contrast, put the same numbers in decimal form, and addition is just as easy as any other decimal number. Line up the decimal points vertically, add digits with the same place value, and there you are. Easy-peasy.

You can replace the battery for yourself, for $0 in labour costs, if Apple didn't choose to seal it into the device. That is price gouging right there.
Apple has a long history of price-gouging on their hardware. Remember when Apple monitors were incompatible with PC monitors, and cost twice as much?
Remember when Apple keyboards used a different connector from PC keyboards, so Apple could gouge you by charging twice as much for their keyboards?
Remember when, quite recently, Apple took away your phone / tablet headphone jack, so you had to buy expensive Bluetooth headphones instead of plugging in the ones you already had?
Remember when Apple started to solder RAM modules into their computers, so you couldn't just plug in new RAM modules, but instead had to pay through the nose to buy the more expensive Apple model with more RAM?
Remember when Apple started to put one miserable USB-C port on their overpriced laptops, so you had to pay even more to buy a USB hub before you could actually use the bloody thing?
The amazing thing about Apple is that they gouge their customers repeatedly, but so many of their customers seem not to notice, or even to enjoy being gouged.
The latter reminds me of Stockholm Syndrome, where kidnapped hostages start to feel love for their captors.

Why would you? Fractions are denominators are doubled when used properly. Anything outside that realm seems unusual and unnecessary to say the least.
The decimal system makes sense but it's not the end all.
All systems have their merits and all have their detractors.
Divide five feet, ten-and-9/16 inches by three.
In the metric system: 1792.3/3 = 597.4

Only in the trades, to make them more usable. But that comes at a heavy cost - you cannot represent all numbers this way. There are "gaps" between the numbers you can represent.
In mathematics you have to be able to represent any number, not just pick and choose a few convenient ones.
Using fractions, there is only one way to represent, for example, the number 19/23. There is no simpler way to write down that specific value. You cannot write it down with a nice easy denominator like 2, 4, 8, 16, 32, or 64.
Not at all - if one insists on working with fractions, and only fractions, then mathematics requires that you have to be able to work with ANY number represented as a fraction.
In mathematics, fractions are called rational numbers. A rational number is any number that can be represented in the form p/q, where p and q are both integers, and q is non-zero.
There is nothing whatsoever that says that q has to be chosen from the list 2, 4, 6, 8, and so on. In fact, if you try to do that, you are now unable to represent some numbers at all. There are "gaps" in between - numbers that you have no way to write down at all.
In North American trades, the gaps can be rather large. Often the gap is as big as 1/8" inch between sizes. In some areas you'll see 1/16", 1/32", or maybe 1/64".
But one sixty-fourth of an inch is still a very large gap by today's standards. Which is why you will never hear Intel describing the size of their latest and greatest transistors in fractions of an inch. Even a thousandth of an inch is far too big to be useful for this purpose.
Wikepedia has an article on current state-of-the art transistor sizes: https://en.wikipedia.org/wiki/5_nm_process
According to that article, current production transistors often have metal features 30 nanometeres apart (pitch).
If you wanted to represent that size (30 nm) in inches, as a fraction, it's (1/846668) of an inch. Not exactly easy or convenient, is it?
Sure. That's why we also have things like scientific notation, engineering notation, SI prefixes, binary (base 2) numbers, real numbers, irrational numbers, imaginary numbers, and complex numbers, to name a few.
None of these more advanced types of numbers exist in the ancient and primitive imperial system.
Notice that all of these advanced types of numbers (except binary) are built on decimal notation. The complex number (2.25 + 3.125 J) will never be written as (2 1/4 + 3 1/8 J), because fractions are ugly, clunky, cumbersome, and inadequate in many cases.
You cannot even write down the everday irrational number Pi as a fraction. Archimedes came up with 22/7, but that is very, very inaccurate.
AFAIK, the only real benefit of the imperial system is familiarity (grandpa used them), and "sunk cost" - there is already a large inventory of stuff made using that system, and it will cost money to change over.
But the longer a country waits, the worse it gets. The bigger the industrial and user base grows, the more expensive it becomes to make the switch.
As we've seen in this thread, many countries are now trapped in a hellish and hideous mess of both systems intermixed. The worst of all worlds.
A simpler example of a similar problem we humans have made for ourselves, is the business of some countries driving on the left side of the road, some on the right. Trillions of dollars are wasted by having to manufacture two versions of every vehicle that needs to sell world-wide. Every year, many people die because they vacationed or moved to a country that drives on the "other" side of the road, and that causes them to make a fatal mistake. (For example, looking the wrong way first before crossing a road.)
The final idiocy here, is that there is no inherent advantage to driving on one side over the other.
If human beings were a rational species, we would long ago have picked one side or the other, and every country would have converted to it. It would save enormous amounts of wasted money, time, effort, and lives every year.
Driving on the left or right may be equal. But when it comes to choosing between Imperial units and the much easier, much more capable, much more logical metric system, there is no such equality.
Sure, if all you need to do is measure wood for a dog-kennel, or buy a container of orange juice, Imperial units will work just as well as metric ones. Imperial units work just fine for a society that has no interest in higher education, math, science, or engineering.
But as soon as you get to more advanced or complicated math or engineering, working in metric units becomes enormously easier, faster, and less error prone.
I think it's amazing that America managed to build a rocket that reached the moon in spite of being saddled with the terrible handicap of Imperial units (I guess all those captured Nazi rocket scientists had to learn inches and slugs and foot-pounds).
Without that terrible handicap, how much further might North America have gone?
Speaking of which, every NASA scientist I know works exclusively in metric units, which are universally used in science, even in America.
Some NASA engineers are still mired in slugs, pounds, and other unfortunate units. Poor sods.

Right. $0 in labour cost + $50 for the battery. Or $50 at Apple. I don't see the difference.

That was decades ago. How's that relevant today?
More drama. It is true that the 3.5 mm connector went away, but nobody forced anybody to buy the expensive bluetooth headphones. I use a pair of wired Apple branded headphones for phone calls and a lightning-to-3.5 mm adapter with my Etymotic earphones if I want to listen to music. The adapter was $9 from Apple. You can get them for about half that at Bezos' Bookstore (and enjoy his corporate practices).
My "overpriced" MacBook Pro has four USB-C ports. I do remember the drama. Now nobody cares because everybody uses USB-C. That's called progress. Sometimes the first mover gets the flack.
My MBP is a pretty nicely spec'ed 13" model. A PC with comparable specs would have cost just as much. And, yes. It did irk me a bit when Apple decided to solder the SSD and RAM to the motherboard. That said, the resulting higher reliability has value. The thinner and lighter devices do too.
I guess I suffer from Stockholm Syndrome then. Amazing how you can diagnose that through a forum post, Dr. Freud. Do you offer any other mental health services? Or is this one of those, "anybody who disagrees with me is mentally deranged" types of arguments? Because I really don't need to be lectured regarding my mental health.The latter reminds me of Stockholm Syndrome, where kidnapped hostages start to feel love for their captors.
I was 200% PC for all of the reasons you mention until I tried a Mac mini back in 2007-8. Now I enjoy having a machine that just works. It connects seamlessly with my phone. It doesn't whine or complain. I don't get ads shoved down my throat or flashy UI features that do more to distract than they add functionality (live tiles anyone?) I like that OSX is UNIX-based and gives me access to a powerful shell terminal/UNIX command line.
I also like that I can use my laptop and phone while I'm wearing polarized sunglasses. And speaking of usability: Apple introduced multi-finger gestures and a large touchpad for navigation at a time when PC laptops had a trackpad the size of a postage stamp that didn't really work reliably for much other than cursor movements.
And I like the resale value. At my last upgrade I sold my then five year-old laptop for $600.
But, hey... We don't all have to like the same stuff.

Mille = 1000, million = 1000x1000, but as a eùropean the american trillion really confuse me because to me a trillion is 1000 000 000 000 000 000
