There are only two essential apps on my Mac. iTerm2, and a browser

When I quit my job and had to get my own laptop I bought a Chromebook. If your usecase is Terminal + Browser they're really very good.

I don't like that I'm supporting the Browser monopoly, but the battery life is supreme++(ARM versions at least), the Linux integration is great, I can run Android apps too(rarely though).

PWA's are integrated really well into ChromeOS so you won't be running one Electron instance per webapp. (My PWA's are Kagi Assistant, WhatsApp, SchildiChat(Element), Discord)
