Fair. Although, I consider Microsoft’s market “Most laptops” since Apple kind of does its own thing and Chromebooks are ultra-low end laptops. Thus Microsoft gets ~95% of the market for themselves.
Personally, I’d say that’s a clear case of monopoly since MS controls this entire segment of “non-Apple, non-ultra low power laptop, PCs”, but you’re right - there are other players. The thing is, they have relatively tiny niches in which they thrive and in fact pose no threat to the monopolist.
But I now I see how you see it as an oligopoly, which is quite valid.
Tell grandma with Parkinson’s to “adapt”. While not as ubiquitus a disability as daltonism or blindness, interfaces should still cater to people with them.
When it’s kids adapting it’s fun. When it’s someone with tremors physically incapable of gently and precisely tapping the exact 5px, it’s just bad design.
I’ve yet to see an accessibility setting for this very valid usecase.
