If you own an Asus Transformer, you're pretty limited in the number of cases available. I initially bought a cheap 15$ leather cover found on an online auction site, but that case didn't fit very well and the Transformer always shifted inside the case, hiding the bottom part of the screen (and the software function keys). I got tired of this case after a month and decided to buy the official Asus case.

Asus' neoprene sleeve is more expensive, but it actually holds the Tranformer very well, and provides a decent amount of protection. It's very similar to Apple's original iPad case, and shares some of its design elements, like the material choice and the weird extended "bumper seams".

The stand functionality is pretty decent and is very stable for video watching, etc.

Some negative points: it's a bit expensive for what it is (but in line with Apple prices), there's no access to the micro-SD slot, and the velcro closure seems small and flimsy, and looks like it would be the first thing to fail. Apart from this issue, this is a solid product, and the best choice if you want to protect your Transformer.
