Own: P4, PP, P5 Use: PP P5 requires such a high resolution that I'm unable to read it. My eyesight is just too bad to be able to use P5 even with large fonts turned on. So, anything that requires a screen resolution higher than 800x600 is not an option for me. As it is, I have to wear a special pair of glasses just for computer work instead of my regular bifocals.
