I'm just about 50 and have been digitally downsizing. I recently wiped my MacBook Pro and reinstalled a fraction of the apps I had prior. To your point, I needed to create an Office doc realized I forgot to install Office. I jumped over to Google Docs. I still haven't installed Office and don't see why I need it anymore. Plus Google Docs rocks for concurrent collaboration on documents.
I find myself being pickier too. Today I wanted a Spotify Mini Player on Mac OS. I tried Web + Chrome Extensions and three Mac Apps. In the end, I deleted them all as they did fit my requirements and will requested an App Store refund for the $5 one I paid for. Funny thing is that I'd pay much more for what I want. That said, I'm back to the huge Spotify window just to be able to see the album cover, artist name, album name, song name, media controls, and the thumbs up button. :(
Another benefit of downsizing apps is for security. We trust developers and there are more and more apps skimming and selling our data, so it's actually less risky to have fewer apps. After typing and thinking about this, I plan to delete a bunch of those 'I might need it' apps from my iPhone.
I think we're in a weird place where we can do much of what we do now on either a 'computer' on a 'mobile' device. We can't do everything yet though. On a Mac, we can run apps for Mac, Windows, Linux, and Web. I think you can even run Android apps on Mac. I don't think we can run iOS apps on Mac, except for our own apps via the simulator.
I focus on Web Apps since they can run just about anywhere. If I need hardware, I can add a Helper App if needed. Native apps make sense when you need to be closer to the hardware. I think PWA apps [ https://medium.com/@deepusnath/4-points-to-keep-in-mind-before-introducing-progressive-web-apps-pwa-to-your-team-8dc66bcf6011 ] seem ideal. I hope the Xojo Web Framework 2 supports PWA...
