Here's a clever commercial created by Colombian company SiceVENDE. Titled "iPad vs paper," the short clip shows us how a tablet device can help us in almost every way but one. Check out the video below for that one scenario during which an iPad is useless. You'll chuckle when you see it.
(For the record, the video is titled "iPad," but I don't think it's an iPad used in the video. Hard to tell, but I don't see the Apple logo anywhere.)
