Have you only got one view/desktop on your N900? can you scroll to the 2nd, 3rd and 4th views/desktops? (that wasn't clear in the video)? Try adding a shortcut... Why not film a boot up, or a power button press or volume button press (does anything happen when you press those buttons)? Or open the keyboard and press CTRL + DELETE/Backspace - What do you see happening on the screen? or again open the keyboard and press a letter on the keyboard - what happens on the screen?
