I've had the phone and armor on it for several months now. I'd have to say, it was really not worth the money. After getting the phone done, the edges around the phone didn't feel right in the hand, you could feel the edges the plastic added and it wasn't pleasant. I remedied this with a simple rubber case, almost defeating the purpose of most of the ghost armor.
Today I decided to just take the armor off after having it on for roughly 3-4 months. The screen had began to get little bubbles in it in some places that was sort of annoying, also I sometimes didn't want to have a case on, and the phone as I said before was uncomfortable.
One thing they advertise when you purchase the ghost armor is it reduces the grease your fingers leave on the screen and make it much easier to remove. I experienced the complete opposite, the ghost armor seemed to almost attract even more grease and made it more difficult to "degrease" the screen. The bare screen works much better, it doesn't attract much grease and it's easier to clean.
I also noticed on the screen that were vertical lines in the plastic running over the screen, which was very noticeable when browsing a website or anything that was white. The final thing I noticed is it decreased the sensitivity of the screen. I had to more effort in making sure my fingers touched down on the screen for it to register, I also think it caused to my capacitive buttons on the back to go all out of whack as well.
Overall I would highly suggested not buying Ghost Armor. It's extremely overpriced and I had very many problems with it. I found no other reviews for the Samsung Captivate specifically on this site (or anywhere really), so I thought I'd throw up a quick review. Sorry I took no pictures, I never really thought about it.
