Yes, I found a guide for getting Photoshop CS6 running in wine (PlayOnLinux wrapper). A recent update to something broke it for me, but it might still work for others.
Libreoffice is essentially full fat Office at this point. If you need any , more than what it offers, you’re more likely than not a computer savvy person already. Photoshop is hard to fully replace though. I ran it in wine for a long time, still haven’t found a good alternative.
There’s currently only two Risc-v laptops that I’ve heard of: The Alibaba Roma and the Balthazar Personal Computing Device. Most development is currently happening in SBCs and microcontrollers.
Just to clarify a few points in #1: CISC has gone largely (entirely?) extinct, so it doesn’t play into this. Arm processors are more efficient than x86, but Risc-v is even more efficient than Arm, giving them an edge in cheap, low power computing. However, some companies have started experimenting with Risc-v for HPC applications, so it’s turning out more versatile than expected. Just this week there was also news of a bunch of companies banding together to develop Risc-v chips for automobile and Telecom, so don’t be surprised if we get Risc-v smartphones and tablets in the near future.
Not OP, but I’ve been running Kubuntu since 2017 since it’s desktop environment looks and works very similar to Windows 7 (desktop with icons, taskbar, launcher, search, options, etc) which is what I was used to after running Windows for two decades before. It’s also stable and sees a lot of mainstream apps being ported to it.
I had a colleague who ran NixOS on his work laptop and loved it. He even held a presentation to the rest of the engineering dept about it. Then IT contacted him and said company policy only allowed running Ubuntu and he had to reinstall.
