I took this screenshot by hitting PrtSc which opens my screenshot app, click Take New Screenshot button, it does, then click Export > to imgur. In a couple of seconds, the image url is placed on my clipboard. (I use Midnight Lizard dark mode addon for Waterfox browser)
Icons on left are single click, quick launch. Three browsers, couple of email clients, catfish file search, package(programs) installer, calculator, Element chat, note keeping app, file manager, another notekeeping app, text editor, spotify, convertAll(unit conversion), twin panel file manager, sublime dev text editor, terminal.
I also have various graphics apps, VLC media player, Private Internet Access VPN. Audio library/players, image library management, PDF/document viewer, Calibre ebook library, word processor, spreadsheets, torrent client and a lot of others. Anything a consumer would need.
Where Linux won't work is in many business settings because most specialized business apps are for Windows and to a lesser degree, Mac. I was in the electric sign business for 25 years and there are specialized graphics programs that are geared for the large scale and will run a cnc machine that cuts vinyl graphics or cnc router. Nothing like that for Linux. There is a LinuxCNC but it's not straight forward to set up. The programs for the sign business have all the drivers for most every machine special made for the sign business.
Banking systems, large accounting systems, inventory systems, Point of Sale systems etc are all MS Windows. Bill Gates cornered the market.
