Twelve South BookArc Stand vs. Official Apple iPad dock

I use the BookArc for two reasons. First it is easier to put on and off which makes a difference when you are laying in bed tired. Second because the BookArc can be used in landscape.

Edit: it's funny but I originally got the BookArc for my MacBook Air and it became the iPad stand. Looks like TwelveSouth thought of the same idea. Which means it doubles as a stand for MacBook Air if you have one.
