It's interesting to note that smartphones and PDAs have been using touch screens for over a decade, and even Sony had the CLIE's. However, this touch screen they're using for the PRS700 seems to be a step backwards two decades. It's almost comparable to my still functioning Palm V.
What happened?
Any, being that it's still new - I've been using this product ever since it was reviewed to be one of the best during the peak of the PDAs.
