I'd recommend Lutris over Heroic both because it runs locally where Heroic is Electron, and because Lutris allows community-based native Linux ports for games where applicable, eg. for Ultima VII: The Black Gate + The Forge of Virtue, Lutris gives you the option of installing that game with Exult instead of DOSbox, for Tomb Raider and Tomb Raider II, you have the option to install those with OpenLara, for Doom 1 and 2, you have the option to install those with ZDoom, for Little Big Adventure, you can install that with the ScummVM runner, etc.
Also, at least for DOS games where you don't have the option to install a community-based modern port, you can use native DOSbox as a runner instead of Windows DOSbox as well through Lutris.
Oh, and one more bonus particularly for GOG games in Lutris' favor over Heroic, is Lutris uses the offline installers so that if anything ever goes wrong with any given GOG game, you can just reinstall from the offline installer where Heroic operates more like GOG Galaxy or Steam in that it's always downloaded from scratch.
Fooyin's a really good alternative and if you can flash Rockbox onto an older iPod that supports that custom firmware, then it'll just function as a normal external drive, no iTunes sync needed unlike with stock Apple firmware.
If you have nothing to lose, ie. if you don't play anything with anticheat or you don't use any productivity software with crazy DRM platform-locking you into Windows, do it, switch over.
The bulk of all games will run in Proton or even vanilla WINE now and the minority that's platform-locked into Windows is anything that uses kernel-level anticheat, if you only play single-player games or even virtual board games like Civilization, those will broadly work fine in WINE/Proton and even in the case of the aforementioned Civilization, those games starting from Civ5 onward even have native Linux ports, but the Windows versions tend to perform better in Proton, and as for productivity software, there's plenty of alternatives to things like Maya, Photoshop, Lightroom, or Premiere/AfterEffects to choose from that isn't platform-locked anywhere, eg. Blender as a Maya alternative, Krita or GIMP as a Photoshop alternative, RawTherapee or Darktable as a Lightroom alternative, and KdenLive or Davinci Resolve as a Premiere/AfterEffects alternative.
Oh, and as for Illustrator, you have Inkscape as an alternative, and for Paint Tool SAI, you got MyPaint as an alternative.
As for a good distro to get you started, Debian or OpenSUSE seem pretty solid for beginners, and Debian Stable at least has a backports repo for newer software, and there's also ChimeraOS if you're building your PC into a games console.
Also, if you're looking for a good Foobar2k or iTunes alternative, Fooyin is great for that, and Whipper's a good CD ripper and basically an open Exact Audio Copy clone, although it's text-based. You could also use CUERipper in WINE as another good open alternative to Exact Audio Copy, which is proprietary. CUETools will work fine in Mono as well.
Alright then MS, (this is hypothetical as I haven't ran Windows as my main OS in years and don't plan on going back) since you want me to trade in my hardware, how 'bout I trade in your OS instead? :p
Stuff like this is why if you develop an emulator, that you're better off self-hosting your own git repos, and optionally hosting on Tor/I2P to completely cover your tracks for good measure.
I was actually using an FD lens adapted to a Micro 4/3 camera at the time, a Canon FD 70-210mm f4 lens to be exact, and was new to running manual glass then, I just thought it was a cute shot.
Prior to getting my first ILC, an Olympus E-M5, which sadly has since died of a stuck shutter, I was using a cheap Cybershot (which I put back into service as a backup and I'm presently using it until I can get the sensor for the E-M5's replacement, a Panasonic GF2, cleaned).
And to be fair, that cheap Cybershot, an H300, really isn't that bad for what it is other than the fact that it's fully autofocus and it doesn't support shooting in raw formats and is limited to JPEGs only.
At least you can still use your older hardware, and at least Radeon cards as old as GCN1 are still actively supported outside of Windows.
Also, old games still exist and will continue to exist in some form into the foreseeable future, legitimately or not.
Like, if you're not into multiplayer games, the Mesa drivers last time I thought still work well, great even, on Polaris and Vega cards as well as even legacy GCN on the Linux side of things, you can still use your RX 580 or 590 with full support going that route, for example.
Element's still Electron-based for the desktop app, given Electron is Chromium and Google has the final say over Chromium, that doesn't make it trustworthy at least in my opinion and I'm sure others' opinions too.
