As someone who started on Windows then went to Macs, I always and still find the "installer" method absolutely horrid.

Why do I have to run an app before I can run an app?? Why do they all look different? Why do most of them insist on shoving other crap into my computer??

Copying a prepackaged bundle is the more intuitive way: You take something from outside and you bring it into your house/put it on your desk.

And then deleting it when you're done (leftover settings files being an optional "pro" step)

Let's not even talk about how "Alt+F4" remotely evokes "close/quit" and other weird shit Windowsers assume is normal.
