Re: The Apple price
The hidden cost of Apple products is that you have to purchase specifications for the future - there's no upgrading. If you pay only for what you need now, the price is great but the computer is a hindrance the moment you need more power. That's a poorly planned purchase.
No, that merely means you're a poor planner. You know what the hardware can do, you know there are things you cannot change so you plan for it.
I have always bought the next size up from what they offered by default and yes, that's more expensive. But I have as yet to run out of memory on any machine I bought - MacOS is a lot more memory efficient than Windows. As for tuning, MacOS seems to do pretty well on its own, about the only thing I occasionally do is clean out snapshots. They disappear after a few days by themselves, but I like things tidy.
What I like about MacOS is that it gets out of the way - I can get things done without a lot of faffing around. Want to share an Internet connection? Two clicks and it's live. Remote control another machine on the network or even elsewhere? For MacOS, it's built in (just hidden in a weird place - Messages, Conversations, Ask to share screen) and all by default disabled for safety. Disk encryption? Click and it's underway, ditto for memory sticks where the encryption is so transparent you forget it's there until you plug it into another machine and it wants the password.
You say restrictions, I say extreme usability - and yes, I use Linux too (I'd want nothing else on a server, OK, maybe FreeBSD but that too is more work than I need).
