This is one of those ideas we see fun through the patent office from Apple that looks as if we will probably never see it happen. It's not that it's a bad idea, but Apple has a tendency to keep all their designs as free of extra pieces and bits as possible. That said, it's doubtful we will see a feature like this on the iPad 2. That doesn't mean it's not interesting to see some of the ideas cooked up by tech companies.
Still, an iPad with a kickstand similar to what is on the back of the EVO sounds rather interesting. Especially when that kickstand can be moved to any position and locked. That's what this application seems to be for, according to the abstract and the drawings.
First, a look at the description:
A support mechanism for supporting an object on a surface is disclosed. The support mechanism includes a joint connected to the object; and a stand connected to the joint. The joint may selectively rotate to allow the stand to support the object on the surface in: a first position comprising a landscape orientation at a first angle between the object and the surface, a second position comprising a landscape orientation at a second angle between the object and the surface, a third position comprising a portrait orientation at a third angle between the object and the surface, and a fourth position comprising a portrait orientation at a fourth angle between the object and the surface.
Hit the jump for some of the pictures make it a little more clear how it could be used:
