I know I am new to this party, but I am really interested. I recently got an at101w and I love it so much, way more than my mx red board..... Anyways, lets keep this updated!!! I really want one and would rather we come to a consensus about stabalizers, I prefer the stabalizers found on the at101w's because they are easy to install and semi-readily avaliable, Unless matias helps out in that regard. As for layout just supporting ansi and iso with the option of not soldering in a win key is the best idea, allows for compatability and semi flexibility.
Just my 2 cents!! But I am willing to help out if need be (I have Autodesk Inventor, if cases would need to be designed).
