I saw a funny review of this keyboard the other day on http://gadgetzine.wordpress.com. They bought the keyboard because the kids kept playing with the regular size keyboard.
Neither the manual nor the Logitech support show how to cause a F1 thru F12 keypress. While this is a nice keyboard and the illumination is cool, for $150 bucks it would be nice if it could perform all the functions of a standard keyboard. I bought it specifically to get a USB keyboard to change the boot setup of a thin client PC; unfortunately I can't hit F10 to enter setup. What a bummer...
