Which cases or skins is everybody using?

I actually have 2 case, both by Poetic through Amazon. The first is just for the tablet itself, Amazon.com: Poetic Slimbook Leather Case for the Asus Transformer TF300 Black with Build In Stand (3 Year Manufacturer Warranty From Poetic)(Has Open Slot for Charger Port)(Business Card Holder is Plus): Computers & Accessories and the second takes the keyboard dock as well. Amazon.com: Poetic ASUS Transformer TF300 Leather Keyboard Portfolio Stand Case Cover for TF300 Black(Included 2 Micro SD Card Slots) (Speaker Hole is Opened)(3 Year Manufacturer Warranty From Poetic): Electronics
I don't use the first one all that much as I tend to leave the keyboard attached but I do use it when using the tablet for presentations. I am happy with both. Unlike some of the other respondents here, I make it a habit of keeping the tablet in a case at pretty much all times to help protect them from accidents and have found that both of these cases serve well in that regard.

Both are made specifically for the TF300 so all the ports and witches are easily accessible.
 
I went with the ASUS Versasleeve. Great, thin, nylon case. But the nylon threads at the edges are fraying after a week of heavy travel (a week long road trip through the mountains and deserts). Seems the Versasleeve is great to keep the tablet safe at home. But for the road, a less fancy, zippered neoprene sleeve might be the way to go. I'm looking at a 10" Roocase now.
