I just got this case this week and it is my third case. The first two being the Incase Silicone protector and the second being the contour flick.
Out of all the cases I've had, this one is my favorite.
Fitment: Top notch. It covers the chrome perfectly and does not leave any of it showing. Buttons are sunk in enough so that they don't get damaged from tossing the phone around but are also easily accessible.
Feel: One of the issues I had with the incase silicone protector was that it not only attracted alot of dust, but it was extremely difficult to take in and out of my pocket. The Griffin Elan Form case definitely slides in and out of the pocket much easier. The leather feels great in the hand and definitely adds to the quality feel that the iPhone has to begin with.
Bulk: Of course any case you put on your iPhone (other than the invisible shield type protectors) will add bulk, but bulk isn't such a bad thing in my opinion. The naked iPhone feels small and has the tendency to slip out of my hand alot. With the Griffin Form case, there is enough bulk so that the phone no longer has a tendency to fall out of my hand but there isn't so much bulk that it is annoying to carry in my jean pocket.
Look: This case looks drop dead sexy. I love it!
Conclusion: I wanted to wait for the incase slider for the 3g but I don't like using my phone without a case and couldn't wait that long. I got this case to hold me over and it delivers. Looks like I don't need to wait anymore cause I actually like this case better than my roommates incase slider for his first gen iphone.
One thing i'd like to note that the leather has started to show signs of peeling but that is not a big deal to me. A case is just that, a case. When the time comes that I need to replace it, I can replace it without hurting the wallet too much. Of course, by that time I'll probably want to trade my iPhone in for the 4G version
