My iPad is a touch screen. My laptop is not. I frequently have both on my podium, switching back and forth between them on the Apple TV.
I can't tell you how many times I have touched the computer screen and can't figure out why nothing is happening. I touch it again. And again.
Then, I hear students snickering... *sigh
smack myself in the head... *sigh
and use the darn keyboard. yikes!
The technological genius strikes again.
