That's more of the key and a difference in philosophy, on Windows it is standard to have a number of programs that autolaunch for convenience, while the linux standard is "lean" with none of that so of course it will boot faster.
I have a dual boot on the machine I'm on, and yes Windows "how I like it" takes a few seconds more to boot, but that is with my 10 common programs starting automatically. If I set up the linux system to do the same it's no better, or even worse. Also my Linux install has at some point (after an update ) decided to hang for 20-30 seconds on some random thing during every boot and I never managed to figure out what that is... Windows hasn't done that to me for more than a decade on multiple computers.
Huh? I've tried from hell and back to get Windows to start as fast on a hard drive as Linux is capable of, using Server 2016 with almost no programs installed, and pretty much everything turned off, and I can't even get to a login screen in the time it takes my Linux install to reach the desktop (and start however many programs you'd want). This isn't a philosophy thing, this is a, Linux is faster than Windows.
I think the one and only valid point you've made is that, for the untrained user, Linux has a habit of being more volatile than Windows. I personally have never had anything particularly break after an update in Linux, (besides GNOME, but that's a load of shit anyways), though I have had things break, not work right, or have issues, mostly on niche hardware like my Surface Pro 3, which has minor issues with the wlan implementation which was intended for laptops that don't get suspended every 10 minutes. This just comes from Linux's more open and modular nature, which is precisely why the majority of its users enjoy it so much.
Don't agree, and it does so at less convenient times. Windows does most updates unnoticed in the background without needing a restart, and for those that occasionally do I couldn't care less that it takes 30 seconds more on shutdown (I don't wait for my machine to shut down, I tell it to do so and walk away so it can take all the time it wants) nor start up since that's always short, but on linux the pesky unattended-upgrades run on startup and often hog 50% CPU for more than 5 minutes, while also locking apt so if you want to install something you can't and have to wait for a frustratingly long amount of time while retrying repeatedly to find when it's finally done.
I think this is the most full of shit thing you said. I'm glad to inform you that my installation of Linux doesn't automatically update itself, doesn't take half the CPU to do so, and will manage to download and install updates for every single program on the computer in the time it takes Windows sometimes just to /discover/ new updates. I don't even have apt nor dpkg on my system, since it's not Debian based. I'd imagine you're using Ubuntu, with a configuration designed to /just work/, and, as I said previously, at a tradeoff of efficiency and performance. Almost every single complaint you have had about Linux does not apply to me whatsoever, and I use Linux on almost every PC compatible I own.
You are taking your one, personal experience with one distinct variant of Linux and applying it to the entire concept as a whole.
Quantity ain't quality.
Fair enough point, but the idea being there might be something better, since there are so many alternatives of varying quality. The program you are using might just not be as good for how you intend to use it as something else.
