I have the palmrest+trackpad protector and the keyboard cover.
I really like the palm rest. It feels just like aluminum, and most of the time, people don't realize that it's there. Because it's not a plastic film, It doesn't feel sticky for me either. The same goes with the track pad. I'm also considering the wrapsol protector, and I'm not sure whether it will have the sticky feeling that most macbook skins like the Bodyguardz and Invisibleshield have.
The keyboard protector is also very nice. However, the annoying caveat is that after closing the computer and putting it away for travel, and then opening it again, you can see some keyboard key imprints on the monitor screen.
I have also used the Moshi iVisor AG, but I found that the antiglare screen will sag a bit, creating a small pocket of space when the monitor is tilted forward.
