I graduated in 2002. Over the course of the 4 year program, 1/2 the class pitched an iPad/iPhone/tablet computer thingy. It was pretty clear where the technology could lead, it was just uncertain when it would be able to.
The thing that irked me was that I designed a tablet that had an acrylic window over the screen that went all the way to edge of the product. Basically like 99% of tablets and phones today. A practicing designer told me that it was impractical for production, I should kill the concept and not show it in my portfolio because it was such a dumb idea. Even designers can have their off days.
