Any other cases which double up as a stand like Apple's case?

There are several. Look at the Marware Eco Vue or the Zoogue case. I also saw this thread a little further down the forum.

When I first saw this thread I was wondering how quickly a reference to ZooGue would be made.

 

If you want one quite similar to the Apple case, but constructed of somewhat more appealing materials, the one discussed in this thread may be what you're looking for.

I purchased one based on the comments in that thread, and it's pretty much as advertised. Not my perfect-forever case, but the price is right, the stand works great (as does the typing angle), and it's thin enough to conform to the curves of the iPad.

I plan on using it for six months or so, while the case manufacturers work at perfecting their offerings (except in the case of ZooGue, which keeps getting shilled as already perfect .)
