Cheaper ALWAYS outsells better.
Not true. It depends a lot on people's financial capacity.
Again, Corvette sales can't hold a candle to Taurus sales. More people would probably rather have a Corvette. But more people buy a Taurus. Does that make a Taurus a better car?
If Corvettes were really better, wouldn't they outsell the Taurus?
Taurus and Corvettes are two different markets: A Taurus is more of a family car, where a Corvette is for males in their late 40's with receding hairlines.
I hate to say it but that first argument is totally gone with the introduction of the Intel Macs. They can run OSX and MS Windows. That makes that particular hardware among the most versatile computer hardware you can buy.
And yet, Intel Macs don't have a majority of the market share.
I can't run OSX on my box. So I guess it is my machine that is limited.
The use of an OS is closely connected to how much software there is. Why run an OS where the number of software packages is limited?
I would rather see OS distribution more even with more emphasis on interoperability rather than MS trying to create their own proprietary standards. With Apple's unixxy underpinnings I think eventually it is going to be MS left on the outside lookng in. (That is my dream. Don't take it away.

)
It's a dream alright!
I also don't think it is fair to call Apples expensive. They usually are packaged with top quality monitors that are of far better quality than much of the cheap crap PC packages sell with. That adds quite a lot of value.
Dell has made a fortune selling PCs where their customers can choose their own monitor. Give the customer a
choice, and you got a winner. That's what Apple is missing.
Or music that people will listen to?
Rather compare it to the hardware and software that people use to listen to music with. MP3 won, and so did the MP3-players.
Remember the brouhaha over iTunes? You want to buy a certain piece of music, but can only buy it at one place, and only play it with one player?
Real smart!
Because quality and sales are not directly proportional. Why does Sylvia Brown's website get so many more hits than Skeptic Report?
...how do you know how many hits each get?
Is Sylvia smarter, more talented and generally better than SR's editor?
Well, she's not prettier, that's for sure!
IBM was worried tha Apple was going to dominate in the marketplace with IIRC the Apple ][ so they set about creating a competitor. They decided that they would use an open architecture and so designed the first PC and booted it with an IBM bios chip. They needed an OS so they approached Mr. Gates who in turn approached the owner of Dr. DOS who missed the appointment prefering to go flying instead. Gates then found a local Seattle guy who had a basic disc operating system based on CPM. Gates bought this system and hired the guy. He was then able to sell DOS to IBM for their new PC.
The new PC was cheaper than Apples and having IBM's business expertise meant applications that were oriented to business. Business not only could afford them but saw the need for them. IBM had a good market.
Later the IBM bios would be cloned and clones hit the market. They all used MS-DOS. Microsoft being in the right place at the right time became a huge company.
It was really IBM who started the PC craze. MS rode their coattails.
(That is the story as well as I can remember.)
Now IBM is a heavy supporter of Linux. Hmmm.
All this explains why both IBM and Microsoft were so successful in the PC market: They understood that proprietary systems was not the answer: To make the market grow, they had to allow competitors to enter the market. It is only recently that Apple has jumped on the bandwagon, too.
