I hear you. I do not play or create games on the PC but have about 40 tabs open across 6 browsers, each with its own major purpose, and often about a dozen docs, among other things using up over half my 32GB of ram and sometimes taxing the 4 GHZ Ryzen 3200G CPU, thank God, but never found Linux to provide the scope of customization and functions I want. Yet it certainly has its place and users.
Like I said, if a server needs building, its *ONLY* going to be a Linux box.
Linux is not ready for the desktop world, unless you want to use a bunch of open-source poorly-supported apps. In the normal professional content creation space, you just dont use it.
Next person that tells me to use the Gimp instead of Photoshop, or Blender instead of 3DSMAX or audacity instead of ProTools will get shot :) No one in industry uses them.
I run Kubuntu which runs the Plasma desktop which has lots of bells and whistles. I would have to start up a couple of graphics programs and/or stream video to push the system.
I used to have a to do list desktop widget on the top left of the desktop in the tan area but I just use my note-keeping program these days and have it auto-start when Kubuntu starts. At the top left on my taskbar(yes, I have it on the top instead of the bottom) are 6 rectangles. Each one is what's called a virtual desktop. I use Ctrl_Alt and Left or Right arrow keys to navigate or just click a rectangle. I have notes and email on desktop 1, firefox on 2, firefox developer edition on 3, Brave browser on 4 and everything else on 5. The screenshot above is desktop 6. All the icons on the left bar are quick launch icons.
$200.00 used Thinkpad from ebay and $0.00 worth of software and I can do anything I need. I run Abiword for a word processor, fully compatible with MS Word files and Calligra Sheets for spreadsheets, fully compatible with Excel files.
