You consider the iPad to be a "far superior reading device" to, say, a Kindle or Nook? I do think the iPad (or any quality tablet with educational software available) could be very useful in schools, but I think it's a far cry from the "far superior reading device to anything else on the market" you claim it is.

I don't think it's far superior for the purpose of simply reading text, I was alluding to all the other capabilities it adds to the bargain. Colour, video, pinch-to-zoom etc.
