I basically found a version of the Targa Tuss leather case/stand for my AirpadX. Here’s a link to the Motorola Xoom version:
http://www.staples.com/Targus-Truss-Leather-Case-Stand-for-Motorola-Xoom/product_332911The version I bought was designed for the Toshiba Thrive, and while it doesn’t fit the complete space, the harder fit at the bottom (when it’s in stand configuration) holds the 10” unit very well and leaves most of the buttons and side gear quite available, at least the version sold around Christmas. Looking at the layout of the revised version has me a little worried if it would still work. The little corner tabs that hold the unit at the top right now covers the power button, which works out pretty well, but the revised design has moved the headphone jack to that position, which would make things bad, since the speakers normally suck already (the speaker openings are in completely different positions).
I actually went to my local Staples to physically try different designs just to see what would work. Still, with the downsides, I like how well works.
