Let me ask you this. Do you really think the S would sell as well if the x were readily available?
x is readily available in our country (turkey)
more people choose S over X despite that (based on the friends i have. literally, i have at least 10 friends that have a series s. and only 2 friends that have a series x)
we're poor folks at this point so that's a contributing factor, mind you
but yes, x is casually, readily available to buy here lmao. and not even for scalp prices, just normal MSRP prices.
it depends on the country I guess. for here? series s definitely sells more. imagine being too broke that 2 of my engineer friends chose series s over series x
the conception that x needing 4k screen also stops more people from buying the x. most folks here had their 1080p screens from their previous PCs/consoles, so they see X as an expensive venture that would need them to buy an expensive 4K TV/screen so they go for series s instead, because that's the marketing niche (btw, i only talk down series s in these forums. in real life, i actually applaud and talk about how much goodie it provides for its price to people and don't discourage anyone from buying it

)
there are also folks who are not serious about gaming but just want to have the new "hotness" and get a series s. my friend is one such example, he has a 4k screen to watch 4k netflix, and he bought series s anyways
