If you're thinking about buying a Pronto, I highly recommend the old non-color one over the ProntoPro color unit ... I have a color (used to the have original), and I get the feeling that Philips had to sacrifice a lot to produce the color display. My screen is less sensitive than the original, the case production quality seems generally lower than the original, and the hard buttons on the sides don't have the tactile response of the original. Maybe I just have a bit of a lemon, but aside from the "cool" factor of having color, I wish I hadn't traded up now.
Just my two cents
