The iLuv Flexi-Clear iPad Case not only adds no bulk to your iPad, it adds tons of protection as well. It comes in a couple different colors and gives you the peace of mind of knowing that if you set your iPad on a surface face up or face down, the screen nor the back will not obtain any damage.
This week I had a chance to look at the black FlexGrip case for the iPad by Griffin, available in black, blue, purple and white. The FlexGrip manages to protect and look good. It's made from silicon, but the slick kind. The case it self is not slippery, but rather it does not stick to surfaces. This is good if you place your iPad in a bag and want to access it easily but bad if you want it to grip on a surface.
I used the case for a couple of weeks putting it in and out of my backpack, laid it on tables, watched content on it, etc. The only issue I had with the case is that the edge flashings do not grip the iPad's glass tightly. This is an issue for me as I seem to collect lint where ever I go. I found myself having to occasionally clean out the lint particles. Also, it is important to note that if you use the iPad dock like I do, it does not fit in the dock with the case on.
Ultimately I liked Griffin FlexGrip for iPad. Just be aware of the looser flashings and that it is the slip not sticky silicone.
