WildWestDesigns Mind sharing what you are using as alternatives? Mind you, I have not done a ton of my own research as to what is out there beside mac and windows (for a production environment. I'm team windows at the shop and at home). Everything that I use (more or less) live in that ecosystem. How are you escaping the grasp of Micro$oft? Or are you a mac house with windows running in a bunch of VMs?
Now mileage will more then likely very from person to person. Only thing that I would highly advise is actually looking into what alternatives (if anyway) are available that fit "your" needs. And a lot of people do still believe that the issues of the 90s and early aughts still exist and they don't, but I digress.
Bare in mind, the easiest factor that was in my favor that allow me to switch is the fact that I rarely get proprietary format files from customers. When I do get customer supplied files, they are raster files, just about any platform can handle those.
I'm actually a Linux house with one bare metal install of Win 8.1. I do have VMs on my main office rig that run Vista, 7 and 8.1. Vista (I do prefer that UI over XP (I hated XP with a passion)), Win 7 and Win 8.1 run in VMs. Within Vista, I run Win 98 (essentially a VM within a VM, surprisingly it runs near natively as if it was on bare metal (the main reason why I always suggest have an appropriately spec'ed out computer for VMs)), but mainly to play old DOS games and some of the early Windows games that I enjoyed playing. I do run one Linux VM that I use for web app/electron development for in house solutions (where able).
Win 7 and 8.1 is where I kept my production programs going. When I first went to Linux, this was more of a "crutch", so I wouldn't lose efficiency and I had something to fall back on if needed. Sometimes there wasn't a Linux equivalent, but that has changed for the one program that that applied to. Now, I do the VMing more out of nostalgia then anything else.
Now, while I'm on Linux as a platform, I do still use closed source programs on Linux (Substance Painter (which may not be around for Linux anymore since Adobe bought that suite of tools) and Caldera (RIP)). The other programs are your usual open source fair. Inkscape (Ai), Scribus (Id, but also used to help prep SVGs for being used as print files), Krita (Corel Painter). I do run Blender, but I never have used a closed source alternative to that, always used Blender. I actually did not use Ps a whole helluva lot, so I don't even have Gimp (Krita is
not a Ps alternative even though a lot of people seem to think that it is) installed and if a distro that I'm on uses it, I uninstall it anyway. Inkscape has a lot of plugins that allow for different things, so Inkscape is actually being used as my digitizing program as well.
I do run other programs for animation and html5 game dev work. But that's neither here nor there for this discussion.
It's not easy to make the switch and not every one can or wants to (and that's fine). I'm just fed up with the direction that some things are going. Don't get me wrong, I really liked Adobe programs, I do like Windows (I really do), it's the extra crap that has gone with it that I don't particularly care for. If that was stripped away, I would still be on Windows, I would still be using Adobe, but times have changed. Either change with them or they change you.
It's not for everyone and it isn't easy, one reason why I originally started those VMs, to help during the rough patches of the learning curve. To me, I enjoy using computers again, so for me it was worth it (that's not going to be everyone, for some they are just a means to an end and that's fine).
