I've used Macs for 5+ years and can safely say "It just works" is pretty much BS.

At least the pain in respect of Finder can be almost totally mitigated by XtraFinder. [1] It's a truly useful addition to Finder.

Think cut&paste, tabs etc, without the slow bulk of CocoaTech's Path Finder. And it's free too! I mostly use the terminal, but nowadays I no longer dread having to fire up Finder when the situation arises.
