I've been pretty impressed with my Invisible Shield so far, I must say. However, I left my iPod on the floor next to my bed last night (Screen face down, oops), and when I woke up I picked it up to check if there were any new apps in Installer... and what did I see? The top half of my screen was covered in literally hundreds of tiny pot holes, which look multi-coloured as they refract the light differently to the rest of the screen. Has anyone else had this problem? I'm not sure if I'm just getting used to it, but it seems to have died down in severity. I only hope it goes away completely, I live in the UK and don't really want to have to pay for shipping to send it back for replacement. UPDATE: after about 4 days they seem to have worked themselves out and have disappeared completely.
