You're talking to SV web devs who's careers depend on and are entirely focused on web tech.

Exactly.

I sometimes wonder if people are so in the bubble that they don’t realize we’re rarely the audience.

Even if this were true, leaving the ChromeOS argument aside (which you shouldn’t, it’s awesome for casual users), it has nothing to do with what I said.

Most software that would’ve been desktop applications moved to web applications a long time ago. Web applications don’t care what the client is running, ergo, the web platform is your competition.

Are they? cough ChromeOS cough

Chromebooks would like to have a word with you.

From user perspective, OS has become a commodity. https://xkcd.com/934/
