A minute seems a bit extreme.  But it never fails to annoy me how a
computer that has a gigahertz clock speed can take several seconds to do
some tasks.  Sure, there are slower parts than the clock, but still...
Something like plugging in a USB stick ought to get recognised a lot
quicker.

And all it takes is for a bad connection, or lead, for something to get
disconnected when you don't know about it (such as a cable wobble), and
you have a device that's disconnected, reconnected, disconnected,
reconnected, in rapid succession.

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
