I still use it to this day because I can't fit my Steam Deck in my pocket.
And I concur that its potential did kinda go to waste. Imagine if we had Shadow of the Colossus and Demon's Souls available on it.
Because let's be honest, most of the population does not even understand the idea of "app store" beyond THE app store the same way they don't understand the idea of "search engine" beyond Google Search. If Chrome only allowed you to use Google Search as the search engine, most people wouldn't complain. This is the same. As long as they can download their [insert Big Tech Company here] walled garden app, most will not complain. But if their phone starts misbehaving because of a rogue app from a dodgy app store or phones suddenly get more expensive to compensate for higher costs incurred by Apple for their development and support of third party app stores and browsers most will complain.
UPDATE: getting downvoted for pointing out the reality. Most people are not hackers. They don't want customisation options. They are happy with a default store or browser as long as it is good enough. If you want options, Android is there
I use vim and nothing about its commands are "cryptic" to me. You want to "go to definition"? You press "gd" as in "(g)o to (d)efinition". What's cryptic about this?
