OK, it's my first mac, just out the box and setting it up nicely. Then I remember seeing a thread about screen brightness. I go into settings and try reducing the brightness a tad to see what effect it has. Because I'm still getting used to the trackpad, my finger slips. It turns the brightness to zero. ie black, very, very black. I cannot see anything to turn it back up 
I don't know any mac shortcut keys! Panic sets in. I try escape and ctrl-z to no avail. Have I just bought a very expensive paperweight?
I'm too embarrassed to log in with my pc to ask for help.
Fortunately after several very long minutes of frantic squinting I eventually manage to make out enough on the screen (beyond my own glossy reflection natch) to find the cursor and locate the adjustment bar and after a few attempts I manage to turn the brightness back on. Phew.
I guess it's not as idiot-proof as I need
Apart from that, it's going well so far
