Can anyone provide a user-review of Trackpad Film protectors? The product information is available here http://www.macimports.com/macimp/tp2.html I would like to hear a report from someone who has given the film a test on a PB or iBook. Specifically; 1) describe the glue used to stick the film to your trackpad 2) the longevity of each film 3) sensitivity of the trackpad after application 4) removal of the film with/without damage (glue) to the pad 5) any warnings? or other suggestions? I have a new powerbook and just want to keep it clean and in top working order. I travel with my pb and it inevitably picks up some annoying, but usually non-damaging dirt etc. This would just make me more comfortable. Thanks.
