This is my review of the Padprop, it's a portable stand made just for the iPad. I first came across this when I was at the Gadget Show Live event. It caught my eye as there were a couple of iPads all at different angles, plus there was a simple demonstration of how to use the product. I know that some of you will be thinking do we really need another stand, and I understand where you are coming from, but I was interested to try this out to see if it was a useful as it was demonstrated.
This is very lightweight it only weighs 50g so it's not like it would weigh you down carrying this around, unlike some of the stands that are currently available for the iPad. It is made from a robust EVA foam, so it does feel sturdy, that's not to say that it can't be damaged if it not used correctly.
Personally I would not use this everyday, as my commute is not a long one, however I would have one of these and would use it when travelling at long distances. I have found it very easy and comfortable to use on my lap as the picture shows above, it makes typing really easy as you no longer have to hold the iPad with one hand, nor do you have to angle the iPad or sit in an awkward position to be able to type. 
On a plane or a long train commute it would be good to have this propped up on the table in front of you. Because you can change the angle very easily be sliding the case down you will always be able to have the optimum viewing angle while the device is still stable.
If you are travelling with this, it also has a slot at the bottom so you can store your earphones inside the stand so you will always be able to have your earphones stored safely with you, personally I think it is a simple but great feature.
I would recommend this stand, because it is very simple and sturdy, I have seen and used the proporta tilt stand and that did not feel very solid, and that was on a desk as opposed to a moving train/plane. Also as I mentioned it's incredibly lightweight to carry especially when you compare it to something like the Griffin A-Frame which is very heavy indeed.
The stand is available for both the iPad models 1 and 2, and is available in black or orange. You can purchase the padprop direct from the site, or via this amazon link
I am always looking at ways to improve, and so I am always interested in feedback so feel free to add any comments here
