This seemed a more appropriate place to put this in than general discussion.

a couple gems from an a+ certification textbook -
"A USB device connects to a USB port or connects wirelessly."
"monitor wipes are used on the front of the monitor screen"
"never spray or pour liquid on any computer part"

youd think that most of those would be covered by common sense....

ps - there is a wireless usb spec, but its more wifi than usb, requires software installs (basically missing the point of usb), and its so rare that ive never actually seen anything that uses it.
