I just wonder at the big mismatch between sales and usage numbers which are about double that. Half the Windows PC's running industrial equipment, and other use cases without internet access?
Without knowing how that site gets their results I honestly can't tell you, but a few others did point out valid reasons for Macs to be overrepresented in that metric. The first being office machines with no internet access, but the second (and what I consider a far bigger factor) being that Apple hardware likely has a longer life span so Mac users don't replace it as often.
I only upgraded to a new iPhone after 5 years and was considering holding out even longer. While I was in the store a woman next to me was upgrading from a 5C and wanted to get an XR. I'm also still using an iPad Air 2 that I got when it first came out and don't intend to upgrade that anytime soon. My brother had one of the earliest quad-core MacBook Pros that he kept for over 8 years and only replaced this summer. My mother had a MacBook Air the she had for 6-7 years.
How long do you think any of the ~$400 Windows computers that every company sells tend to last? Dell has a 15.6" (1334x768) 2 core Celeron (1.8 GHz) with 4 GB of RAM and a 128 GB SSD for $320. Coincidentally the specs on this actually line up nicely with my five year old iPhone 6S which had 2 ARM cores at 1.86 GHz, a 1334x750 pixel display, and 128 GB of solid state memory. It only had 2 GB of RAM though, but I suspect after accounting for operating system usage, the amount left for the user would have been similar.
Quite frankly, I wouldn't have accepted a laptop like that 5 years ago and if I had bought one with those specs I very much doubt it would have lasted me 5 years. The worst desktop I can get from Dell is a quad core i3 with a spinning hard disk and 4 GB of RAM. It's $380. That isn't lasting me 5 years either.
Not to many people here would buy anything like that from Dell or anyone else, but there are a few posters that build low-end PCs that they either give to family/friends or try to sling as a way to making a bit of money. There's a
6-year old AT article about building a budget PC that puts together a PC that costs $400 that's in some ways better than the $380 Dell model since it has 8 GB of RAM and includes an SSD for the OS. The RAM and SSD prices have probably come down enough to allow for an entry-level APU quad core APU.
However, the average price needs to account for the expensive high end computers that are being sold and if there are enough of those and at a significant price difference, it can distort the average. If you had a market where 9 people bought a $600 computer and then add 1 person who buys a $1,200 computer, the average sales price goes up by 10% (to $660) just because one person bought a computer that was twice as expensive as the old average. However, the more interesting effect is when you keep the average sales price fixed at $600. In that situation those other 9 individuals would have to have bought $533.33 computers to make it average out. One person essentially eats $66.66 of value away from each of the 9 on the other side of the mean.
Now that's a simplistic calculation for the point of illustration, but it's not too far off of reality. I found two stats from Statista (full details require membership) that put the average personal computer (I believe this includes laptops) sales price in 2019 at $632 and the average desktop sales price in 2015 at $544. That alone doesn't tell us much, but we can make a reasonable estimate about the average sales price for Apple's computers.
If we use the 7.9% market share from the previous article I linked that comes to about 5.388 million Macs sold in that quarter based on the estimated global PC shipments.
Apple's financials for that quarter (note that for their company the fiscal fourth quarter corresponds to the third quarter of the actual year) report the Mac division revenue as $6.991 billion dollars. That's an average sales price of roughly $1,300 for Apple's computers. For convenience let's assume 2.1% of the market are PC sales that have a similar average sales price. This means with 10% of the market at $1,300 ASP, the other 90% needs to buy $557.77 computers to make the average work out to $632.
Of course the bottom 90% of the market doesn't buy just $550 computers. There's some number that are buying the $800 computers that Dell and HP sell. If that's 10% of the market, the remaining 80% needs to be buying $527 computers. If it were instead 20%, the remaining 70% has to buy $488 computers to balance it all out. The exact mix of sales isn't important, but we could estimate that. However, the $500 Dell computers aren't all that much better either and still include a spinning disk. Backblaze put out
some information on their website which indicated that 22% of their drives failed within the first four years. While it's true they're probably using the drives more, they probably don't get quite the same level of awful that goes into these OEM machines either.
Suppose we have a hypothetical spread (which actually winds up looking close to a normal distribution which the actual market likely resembles for reasons I won't get into, so this is a decent approximation) where the top 10% buys at $1,300, the next 10% at $900, 20% at $700, another 20% at $600, and then 20% at $450. That still leaves 20% of the market that needs to buy for an average of $310 to balance the numbers. That's below the minimum you pay on Dell's website, but that part of the market exists and may be much larger than just 20%. Some people aren't just buying the current garbage, but last (or perhaps the one before that) year's bottom basement closeout deals that retailers want to get off the shelves.
Walmart has some utterly ancient hardware (based on what's there I suspect a Core 2 Duo is the minimum CPU you can get to run Windows 10) on their website (though a lot of it from third parties selling through Walmart) for $200 or less. There's one that's being sold refurbished for $88 which includes a 13 year old Conroe CPU. The product description lists one of the key features and benefits as being able to store 22,000 songs.
I don't know how much of that is original parts or cobbled together from dozens of salvaged boxes considering how hard it would be to buy some of the components. All but one of the 8GB DDR2 kits on Newegg run more than the $88 for the computer. Frankly though, it doesn't matter if the HDD or whatever shoddy power supply is in that thing craps the bed after only two years, or if the amount of malware (pre-installed or otherwise) has made it unusable before then. Just throw it out and get a new one, or well a new ancient pile of junk at any rate.
The cheapest thing I could find on Walmart's website that's actually sold by Walmart and not just through them is a $169.00 laptop with a 4-core Atom CPU (coincidentally one of the last made for consumer products) and enough flash storage to hold the operating system and quite possibly five high scores in Solitaire. It's got 4 GB of RAM, but the Intel spec sheet says it's going to be a single stick of DDR3-1600. I don't know what kind of battery it has and the only information I can find just says 9000 mAh without any mention of the chemistry. I'm thinking lead-acid.
I can't imagine trying to use it and it took some digging to even find relevant benchmarks for it and something to compare it to. Notebookcheck says it gets 31/101 points in Cinebench R15 single / multicore. AT's CPU Bench only has a single entry even close to that low which is a Conroe chip (curiously one just slightly older and .2 GHz slower than the one in the $88 Walmart special) that gets 54/102 points in the respective benchmarks. I would imagine that these fantastic kinds of system hang for at least 15 seconds out of every minute of use.
If you were to use one of these systems for two hours a day and you earn federal minimum wage it only takes four months before the time one of the computers has taken off of your life waiting on it to do something could have been spent working to buy the $400 budget PC from 6 years ago described above that can get 110 points in the Cinebench R15 single thread test! There's
a more modern take on a $400 build that includes a Ryzen R3 1200 (135/482 Cinebench R15 scores) and GTX 1030. Obviously if we dropped the gaming focus (and discrete graphics card) and swapped in an APU it'd be easy to get an SSD for the OS.
I've wasted far too much time on this post and researching all of the various parts of it, but it was certainly a fascinating rabbit hole to go down.
TLDR: There are a lot of trash heaps being sold in the Windows PC market. They probably get replaced every 2 years with another steaming turd out of necessity. The people who buy such awful machines may repeat doing so 2 - 4 times before a Mac user gets a new machine.
