Like stated above, any machine can be used as a “daily driver” depending on what you want to do…
For me, almost 100% of what I need to do can be done on a 32bits laptop with 1 gig of RAM although it’s not my daily driver.
Google E-mail and web calendars can be managed from Thunderbird- but that application uses a lot of RAM.
I can do editions using google docs or MS Office 365 free accounts- but not as smoothy as working with LibreOffice.
For modern web apps I would advise using at least over 1 gig of RAM and, ideally, at least a dual core.- using those specs, at least for now you can use probably any web app in existence- which is the single good out come from every single servince being “transformed” into a web app- you can run video streaming services, music streaming services, video game “remote play” services- like Google Stadia or the equivalent Microsoft service, Instant messengers, Video Chat services, Office applications (like google doc or MS on-line Office), or now, even Ms Windows itself (if you want to pay a small fortune for it) inside a web browser… Basically once Adobe’s products make the move to web apps, for the normal user there won’t be much difference if the OS is Windows, Linux or whatever.
In my case, for office work, and work with on-line pdf’s, almost any single computer that is able to run Firefox esr and LibreOffice will do for me.
