Thank you for your reply!
Is it really worth it to have your entire setup, all of your devices, made by Apple? Why is the benefit of having a 100% Apple environment?
Aren't there benefits to have a Windows or a Linux computer in the mix?
Preface: Asking such questions of a very biased crowd will overwhelmingly get you very biased answers. This is basically Appleville where Apple Inc is up to God for some people. So naturally, you are going to get 80+:20- passionate arguments why all Apple everything trumps anything else. If you went deep into an Androidville forum and basically asked Android vs. iOS, you'd get overwhelmingly passionate Android answers. If you went into Windowville forums, you would get overwhelmingly passionate Windows answers. In all my virtual travels through all such "villes", there are none as brand passionate as Apple fans... who seem to have some personal mandate to push Apple everything no matter what... and fault anything that competes with Apple no matter what.
That offered, let's get to your questions:
100% Apple generally delivers a "works well together" experience, strong compatibility, pretty good interoperability, shared services that work well across hardware, etc. Learning how to do things the Apple way will generally work the same/similarly across Apple hardware. Embracing the walled garden means that things that work in the garden will generally "just work" with other Apple products too.
Is it worth it? That's a personal decision. You have to define worth for yourself. There are some here who might trade a kidney for something from Apple. I suspect if it came down to food & shelter vs. new iPhone, a few would choose starving & homeless to get the phone. Etc. Is
that "worth it?" For me, I'd say no. But worth is definately eye- or wallet- of the beholder.
Benefits of having a Windows or Linux computer in the mix comes down to what software you want/need to run. All it takes is
ONE Windows-only piece of software that you need to run to rationalize having something that can run Windows. The vast majority of computing in the world is done on Windows computers. There are countless applications that only run on Windows. If you need 100% compatibility with Windows files, opening them in something on Mac- if that's even an option- and then exporting them back to a Windows format does not guarantee 100% compatibility. Even a same-name app available for BOTH Mac and Windows may not be 100% cross-platform compatible.
So to this Windows/Linux question, ask yourself a simple question: is there anything I want/need to do on computing technology that will
require Windows/Linux? If yes, you have the answer to that question. If no, you might be able to get by with workarounds like using a public Windows computer for rare-need access, borrowing some time on one for free from a friend, work (Windows) computer, virtual Windows solution and/or something like Parallels using Windows for ARM.
In my own situation, I make my living with computers. I have clients who need me to be able to open Windows files and run niche Windows apps. I much prefer using Mac as much as possible but need is need. Until Silicon, Apple offered the ultimate solution of a
single computer able to run BOTH platforms natively. With Silicon, that tremendous benefit is fading as the old Mac works toward its demise.
Windows for ARM is not full Windows, so the hope of a revived bootcamp option with Windows for ARM is not necessarily scratching all itches... IF it ever comes. Parallels type options are also leaning on Windows for ARM.
My solution was to recreate "bootcamp" the old fashioned way... with a dedicated Windows computer.
Since cost is a concern in your post, choose your key accessories carefully. For example, Apple's Studio monitor is high praised by Apple people but it is basically a one-input monitor. If you need a separate Windows computer, you might want to seek out a monitor with at least 2 inputs so you can easily switch out without all the unplugging-replugging.
For me, that meant Mac Studio + a Mac-mini-like PC + a Dell 5K2K ultra-wide monitor. This monitor has a KVM-like switch built into it so it can share keyboard and mouse (instead of needing 2 separates of each) and multiple inputs so I can simply leave the little Windows box and little Mac box hooked up. It can even split screen so I can have Windows and Mac running side by side at the
same time.
If I also needed Linux running separately too, there's another input for that available. Nutshell: one monitor + keyboard + mouse to work with up to 4 different computers without unhooking/re-hooking cables.
Since Mac And PC tuck in behind the monitor, the only visible brand mark is on the monitor. Thus, others may assume I have a Dell iMac-like all-in-one, running something that looks like macOS (because it is macOS). But if the main decision is driven by what other people think, the "ville" in which those other people live will drive the decision. I don't care what other people think- I just want a great Mac and need a solid Windows system and this was a good way to get both without lots of hardware duplication.
All that offered: if you think through all of the stuff you want/need to do with a computer and Macs can cover
ALL of those things well, then you probably can go "all Apple" and be fine. Yes, it will certainly
feel more expensive (Apple's big fat margins are indisputable), but Apple stuff does tend to be well made and perform well for many years. However, if you know that you need at least ONE thing that is Windows or Linux only, you can't go all Apple. If most of your want/needs are Windows/Linux based, you might not need Apple at all... or perhaps make your purchases Windows/Linux focused with maybe an iPad to get a dose of Appleville too.
Lastly, Intel Macs are still for sale new and as refurbs... the latter at a modest discount. While Apple people would see them as the past, they still run latest macOS just fine and offer bootcamp for 100% Windows compatibility. So one option would be to buy one of those so you have "one computer to rule them all." Since Apple still sells Intel Macs as new, macOS will likely still be compatible with Intel Macs for the next 5+ years before "features only for Silicon" make them really feel old. This could be a way to see how much you can do with "100% Apple" while still having a cheap, very good fall-back to Windows & Linux when/if needed.
Since Windows is generally backwards compatible much longer than macOS, even if an Intel Mac purchase is macOS unsupported in 5+ years, it can become a dedicated Windows machine for probably another 5 and you can add about a M6 Mac if you are "mostly Apple" by then.
