Try the applications and judge for yourself. There are tons of them. Most people are probably OK with the performance of apps like Spotify, and have never come close to exhausting their memory or disk space. I think being able to use HTML and CSS for layout, but with full access to native APIs, is a huge reason electron keeps winning despite the hn complaints. I’d be happier without it being JavaScript-based, but there are nice languages that compile down to it, like Elm and clojurescript.
