I, too, have been thinking of getting an InvisibleShield for my white MB, mainly to thwart the discoloration issue, if it ever decides to show up. I've had an InvisibleShield on my 5G 60GB white iPod for about 6 months now and I think it works great...
*however*
I have two issues:
1. It's pretty challenging to apply and get the bubbles out...plan to spend some time if you're like me and really anal about the nastiness of bubbles, dust particles, etc. Maybe application on a larger surface like the MB would be easier, I'm not sure...
2. After just a month or so of use, the InvisibleShield on my iPod began to show an accumulation of dirt and debris on the sticky edges of the Shield material, particularly on the top of the front shield. Has anyone else seen this?
I would love to get the Shield for my MB, but I'm really just afraid of #2...😕 😱 I second the motion for pictures of MB's with Shields on! 😀
