I dont think Photoshop and Roblox work on Linux at all (Roblox does through Sober right now but probably not for long). Buying another computer will not change that (and iirc mac os also supports dual boot).
However if you buy/build a good enough pc, you can run windows in a vm and use roblox/ps without dual booting.
If you dont strictly need a laptop, then yes I would recommend you build your own desktop pc. But if you do, AFAIK xps and thinkpad line of laptops have pretty good quality. The higher end surface laptops are also good (but very expensive). I cant really recommend much else without knowing what features you expect.
Its really a shame Huawei went for a closed source OS on phones (and probably laptops in the future if not now) instead of Linux or another open source OS (they even started with an open source version of their os). I hope this harmony os doesn’t take up in other countries or we would be going backwards.
Not Sunshine but I personally use Ark. PeaZip has a lot more features (its like WinRAR but FOSS) but I don’t need them and so I use Ark which is more focused. I still keep PeaZip around in case I ever need it.
Its written in Rust, is a completely new code base so not held back by tech debt, and is a clean DE while still being fairly customizable even now.
I personally don’t care why system76 felt the need to code a new DE from scratch, Im just glad they did it. It has given us a whole new ecosystem of GUI toolkits, apps, etc. for linux written in Rust.
One way is to donate to devs who are working on some specific features in the Linux kernel. The two I remember are Hector Martin who lead the Asahi Linux project and Kent Overstreet who is the main dev behind bcachefs, a new CoW FS.
But I guess this only works if there is some dev already working on a feature and is accepting donations. I wish we had community linux project or something similar which was funded by donations and hired kernel devs to work on things the community voted on.
Delta chat is based on top of email (i.e.SMTP, IMAP) so its like sending emails but in a chat format and encryption on top (and some more stuff).
I wonder when Ubuntu will make the shift. They are the only ones left on AppArmor at this point (tbf they have been maintaining it alone anyways).
Havent tried it but it seems like you can make it work: https://appdb.winehq.org/objectManager.php?iId=17&sClass=application
