I did receive the Poetic Slimbook and I am pleased with it. The picture on this thread is of course not correct (it is updated now on the amazon site). There is no microsd card holder (nor would there be any need for one). The fit is nice. It closes completely. Smart function works as expected.
I suspect the Tribook to be similar to the Slimbook. Probably the only difference is the stiching and maybe material.
I did also order one from Exotek posted above. I will get it in August.
