Miguel,
I understand Bobj will be shipping a version of it for the TF700T around September 22nd, so I'm going to order one when it becomes available. It does provide a little bit of bulk on the edges, but I actually prefer it to protect the tablet. The grip is solid, won't slip, and the tablet just feels better in my hands. I also feel it has enough padding to keep from busting the screen if I accidently drop it.
As I mentioned above, I initially bought their TF300 Silicone Case from Bobj on Amazon for my TF700T, and I love it. The model for the TF300 fits fine, it's nice and tight, but I did have to make some changes to it with a razor knife in order to open up the speaker area, modify the SD card slot and a few other items that ASUS changed.
I did not mind doing that because it was more important for me to have some sort of protective case rather than nothing at all. It also keeps the back from getting scratched up, so in general I'm real satisfied with the product.
UPDATED 10/26: Just received the new TF700T Silicone Case, it's on Amazon.
