I had purchased some for my 5500 a long while back... it wasn\'t the thin/flimsy plastic screens, it was more of a thicker plastic screen that was a real pain to install, but once on, it was very nice. I felt much more comfortable using the 5500 knowing that the screen was protected. It did reduce the brightness of the screen a little. I can\'t remember where and which screen I bought though... I\'ll see if I can find the details to post here.
I\'m now looking for the same kind of screen for my 760. Especially since the screen is so damn nice, and because you can flip the unit around and have the screen exposed (in view mode). I also haven\'t found a case for it yet, so any protection I can find for it would be great.
