HEADLINE: Lightweight by default - don't follow the Windows/Mac crowd
DESCRIPTION: GNU/Linux - X'ish desktop environments systems in general and window managers in particular - used to have a certain way and freedom to be able to do things. Around 2000-2005 I was quite happy with FVWM, KDE3 etc. The window managers allowed me to do things that weren't possible with Windows or Mac. (Focus follows mouse, configurable behavious, handle many windows with ease...) I wish Windows or macOS won't be considered as ideal solutions and GNU/Linux just being a bad copy of that. If that's really the best thing, then it's a better idea to actually use MS Windows or macOS - I use the latter since 5 years almost exclusively. Just recently I started using Linux (Xubuntu) again privately on an older computer and at work as well. (At work we don't have Macs)
Please come up with your own ideas - nobody except "computer experts" use Linux on the Desktop anyways. You could go from there. Also looking at Xubuntu, it's a cool system. I really like it because it's fast, I can work with more than 5 windows comfortably. Unfortunately its bluetooth config is worse - recently I had to login to Cinnamon to make my Bluetooth mouse work again. Same goes for multi monitor, it works okay. ;) That means: when I disconnect my laptop from the external screens, open the display and go to the meeting it's black. I have to shut it down if I want to use it. (Power button or SysRq...)
So yeah, if Windows gets got enough (read: they finally get rid of all these freezes and things that just stop working) and they Opensource even more stuff, why not use Windows? I must admit, I'm no Opensource prophet so my primary reason to start switching to Linux around '98 was because Windows was mega buggy, slow and not nice to use on average hardware when the installation was more than a few months ago. IMHO true Opensource people use Debian, Arch or some unusual combination - like Windows as main OS with Emacs and Arch in the VM like a friend of mine.
Again is a time with so much potential for Ubuntu Desktop because devs are increasingly unhappy with macOS.
