Over the holidays my Prono experienced the cracked screen of death. I was able to order and install a G revision from Frontier Electronics. I have not seen a large difference in brightness or sharpness, but the new G Rev is much more Touch Sensitive than my original Pronto. One difference that has been noticed. When I touch the screen to 'wake-up' the pronto the screen flashes black before the display appears. I don't think it is anything to worry about but I will keep you all posted.
